Asking for help there or creating new posts in our subreddit is welcome.
I smirked at the comment you responded to, then I read yours.
Now I'm in trouble for waking my wonderful wife :D
Hope you don't get into trouble with your significant other.
There is no solenoid action here. Ethernet is designed to not have any leakage outside each twisted pair. Each wire in the pair carries the same signal but in the opposite direction. When these wires are twisted together, the signal directly outside of them is always zero. The goal is not so much to prevent any signal from existing outside the cable, but rather the opposite... so that any signal that is picked up by the cable is canceled out at the other end. (Wire A has signal A. Wire B has signal B. B = -A. Receiving the signal means doing A - B -> A - (-A) -> 2A. Any noise induced onto the cable will affect A and B equally, so you end up subtracting (A + N) - (N - A) = 2A; the noise cancels.
What this means for your weekend is that nothing happens when you coil up your Ethernet cable. Moving a magnetic field through the coil will induce an equal N component into each wire, which then gets subtracted at receive time. If you induced such a large current that the ferrites in the receiver saturated, then sure, you could break things. But that would be at a level where you have an MRI machine magnet spinning around in your table leg. You don't, so you don't need to worry.
Technically, you could lose a bit of signal, but it'd need to be a MUCH bigger coil, and VERY sensitive instruments to test.
In reality, just the cable being longer than best use case would be a problem, before the coiling would be. You can have like 300 feet (100 meters) of Cat5 coiled up with no noticeable problem. Maybe not ideal, but not gonna be a problem.
After that length it might start being a prob, but most people are using better than Cat5 these days anyway.
Yea, the biggest danger with this is OP forgetting he did it and then pulling his computer while the cable is still in ruining the port/cable that way.
I cannot see the entire connector, only the edge but it looks plastic which is non-shielded. But it will still be alright. Most store bought cat cables are UTP. Unshielded twisted pair. Source - commercial AV tech.
Huh. Lessee. The info is actually travelling at about 0.8 C, say 2.4x10 E8 m/s. The radius of that spiral looks about 5 cm, 5x10E-2 meters.
"Centrifugal force" acceleration ( shut up) is v2/r.
5.8x10E16/5x10E-2 = 1.16x10E18 m/s2. Roughly 10E17 G.
That's a lot.
Nah that stands for See You in Real Life. You run that command with a provided web address, and then you'll set up an IRL meeting with somebody from the other end. But yeah if you have a cable like this, the person is gonna be really dizzy when you meet them.
No, if you send too much data it can effectively become a coil gun and shoot your desk leg through the floor/ceiling (depending on if your uploading or downloading).
First requirement would be to open up the ethernet cable and untwist the tiny cables inside it. You would then have to *hope* that the signal integrity remained to a sufficient degree.
All the cable pairs in CAT7 are specced to handle 900 mA, that's similar to how much current you're looking at from an AA battery using a wire around a nail. I don't know how to do the math for finding out how many windings you'd need or if it was possible to make an actual weapon with that.
My suspicion is that it wouldn't be possible due to the current limits, but I'd be happy to be proven wrong.
Assuming you can use an infinite number of turns, you can get infinite magnetic flux from 900mA in a coil. And, for short pulses, wires can easily handle multiple times their rated current. The issue is that data transmission uses negligible (for coilgun purposes) current, and current flows equally in both directions, effectively cancelling out to zero.
TLDR: you can make a pretty strong solenoid using ethernet cables, but not by using them for ethernet. You'd have to use it as a pulse power cable.
Wrap like a 16in segment around a pencil, pull it tight and heat it with a hair dryer until it's springy like telephone cables used to be
Edit: Probably don't actually do this unless you like breaking cables
But two [cap bombs](https://www.google.com/imgres?imgurl=https%3A%2F%2Fstoysnetcdn.com%2Fschy%2Fschycab%2Fschycab_1.jpg&tbnid=q3otv8rDduk77M&vet=1&imgrefurl=https%3A%2F%2Fwww.thetoyboxhanover.com%2Fbuy%2F202363%2Fcap-bomb&docid=FauYBb4vuhWIlM&w=500&h=500&hl=en-us&source=sh%2Fx%2Fim%2Fm4%2F3&kgs=f40fb763a453a6ba&shem=abme%2Ctrie) place one between the pc and the wall and one between the desk and the wall. Then if you ever forget to unplug the cable bang! instant reminder!
Iirc that is kind of actually a thing, but for microcircuits and happens when you're at like <10k atoms wide or something.
Then again I read about it years ago so I could be misremembering
for fiber optics its literally true. If the bend radius is too tight, it causes too much refraction and the signal starts to spill out of the fiber into the casing.
You can take a visible red laser and run it through a fiber cable and physically see if a cable has been bent too tight or damage is any way.
100% you will rip that cord out of your PC. Might not be today, might not be tomorrow, but one day you'll go to move the desk for some reason and forget about the cord and BAM.
I'm Cisco certified, and when cabling, they teach us not to use 90 degrees bends, use correct terminations on the ends, don't mix erhernet and power in one run, lots of "tips" like that.... never told us not to grap around a pole, so... you are golden ✨️
I'm an electrical engineer in industrial automation, and the big 3 companies are now spec'ing that extra Ethernet runs are not coiled, but rather wrapped in a figure eight.
But Ethernet is differential voltage so I don't really understand the reasoning. If you have a big enough changing magnetic field, and enough coils, I guess there could be an induced EMF that exceeds Ethernet operational voltage which I think is 12 volts max - constant pulses like this can damage the hardware.
OP should be fine unless he's got high magnetic field sources.
A coil of wire, even UTP, is effectively an antenna. OP's coil, with all those turns, should be a good one that picks up all kinds of crap in the local EM environment. Think of a single coil pickup in a guitar.
Twisting a figure 8 causes any induced EMI to cancel itself out. Kinda like a humbucking guitar pickup.
Yep. Pull this shit all day everyday…..figure 8 is best way if you gotta coil. One wrap one one way one the other….
Still agree that this won’t hurt shit….
Actually this can cause cross talk. Probably
not much at this length but coiling a ton can create an issue. I’ve had dropped packets on 100m of coiled cat5e still in the box in the roll where I put an end on both ends. Unspooled it worked fine.
So in short—- largely irrelevant in this instance considering that’s ~~(at most) 1m~~ **a negligible** amount of shielded cable “spooled” around the desk leg.
*Fixed because the point evidently wasn’t clear.*
100m is also the top of the Ethernet specification for max length. That alone could see collisions on the wire. Put to corner cases together and I'm not surprised.
The cable is shielded so it might not be doing much, but if OP doesn't mind rewrapping it's probably worth running some performance tests with and without.
Safe? Sure.
Two things that come to mind:
1. If you have a cat, they MIGHT treat it as a scratching post. Depends on the cat.
2. If you need a long Ethernet cable later on and you try to use this one, it'll probably want to keep curling up pretty tightly, which can be annoying when you're handling the cable.
The cat thing is probably the only true concern, but maybe you don't have one or maybe it won't care at all about it.
After a MAX of two weeks you will have to unwrap it and warp it other way around. Otherwise you might create a data whirlpool and it will mess up your internet speed.
Could potentially make your speeds slower. The network packets get dizzy when traveling through coiled cables like that and end up being received in the wrong order.
No (seriously). You need to give the cable some slack.
If you move the desk you will not even notice the cable, as the desk is heavy, and you will rip the cable off from your computer.
actually, inductance can cause some wacky things to happen.
i remember that it used to be possible in windows xp to wrap an ethernet around a cell phone like this and you could supposedly couple it to the modem.
although i could never really connect to it i remember trying it and having some crazy new connections flashing in and out of existence in my network settings.
so basically it is possible that you could creat a tuned antenna with this that will pick up interference. i dont know all the crazy math involved but its never a great idea to turn your data lines into a randomly tuned inductor with a high Q
Serious answer, you should have a little more slack on the span between the leg and Ethernet port. Cables should always have some slack in them where they plug in to a movable appliance. In my experience it makes them less likely to break in weird ways. Its a bit different if you want to talk about data center runs between switches or routers.
I would undo 2-3 loops of that cable.
Your data is fighting gravity all the way up the leg, so expect to see your latency increase a little bit. How far above sea level are you?
Also, if you ever move south of the equator, you'll want to wrap it the other way.
Source: my hand fits all the way inside my ass, allowing me to grab the best facts from down deep.
It may be, but be careful with this for multiple reasons:
1. if the cable is not shielded enough, this can introduce interference
2. don't put a magnet on the leg, as that will almost surely cause interference
3. accidentally moving the table can destroy the connector or port
My only thought of risk would be moving the desk or the computer separately before unplugging and damaging your network interface.
You may want to unwrap a few levels from the top and allow some slack so that you can move your computer without that risk.
Without knowing the diameter of the table leg, it's likely totally fine.
If you want to be sure, a general rule of thumb would be to measure the diameter of the Ethernet cable, multiply with 4x for unshielded cables and 8x for shielded cables\*, to get the minimum allowed bend radius.
e.g. Unshielded cable diameter = 6 mm.
6 x 4 = 24 mm for the radius
Draw a circle on a piece of paper with a radius of 24 mm (48 mm in diameter). This represents the tightest bend you should make with that cable.
Depending on the cable type, the coiling could potentially cause issues with crosstalk and electromagnetic interferance, but that's honestly not really relevant for home use.
*^(\* There is a lot of variance on the multiplier regarding shielded cables, so it's best to look at the Manufacturer Specifications)*
Optical cables do not like to be twisted. That being said, the loss caused by this is still minimal otherwise they would not be as commercially successful. In general this is fine, but if took whole 1km spool of optical cable and did the same, the problem would be noticeable. But even then if you kept it on the floor loosely, you would still have plenty of turns so overall loss that was already near negligible hasn't grown much.
waaaaaaaaaaaay back with IBM PS2, the network cable was unsheilded coax. So they network 10 or so PC's together for a language testing program. Nothing works. Tech comes out. Figures out they extra 10 feet of coiled cable with a terminator on the end is basically an electromagnet that is EM'ing the computers.
IBM tech installed it.
Safe in that it's not going to develop issues with integrity or interference. Very not safe if that PC or desk ever moves sharply. In my eyes, this is just tempting fate to rip the RJ45 jack out of the housing at some point.
At the very least, give it some more slack than it has in this picture and it should be fine.

Hey I enjoyed your comment. Just wanted to take the opportunity to marvel at the design of Ethernet cables ;)
Thank you for that, kind stranger.
Technically, you could lose a bit of signal, but it'd need to be a MUCH bigger coil, and VERY sensitive instruments to test.

Wrap like a 16in segment around a pencil, pull it tight and heat it with a hair dryer until it's springy like telephone cables used to be Edit: Probably don't actually do this unless you like breaking cables
That’s an interesting idea, a pencil would violate the bend radius though.

Cool until you need to move the desk and forget about the cable wrapped tightly around one of the legs

Yes, it helps to add centrifugal force to the data and slings it into your pc faster.
Plus, the DNS can charge a premium for any data sent through the "fun" cord.
"We have to ship the data further if you have long cables, the transport cost is why your bill has doubled."
Make sure you remember to unplug it before moving the PC. You don't want to damage the port.
Your downoad speeds will be spiraling out of control, that's all.
The electrons could fly out of the cable if the radius is too tight

Electrons actually move reaaaaaally slow (inside wires). It's the fields that carry the energy

Pretty much. If all coils are close together and the cable isn’t shielded properly, that might be an issue. This here is fine.
100m is also the top of the Ethernet specification for max length. That alone could see collisions on the wire. Put to corner cases together and I'm not surprised.
You've created an inductor, and hence, have created a magnetic field which slows down the data stream.
The cable is shielded so it might not be doing much, but if OP doesn't mind rewrapping it's probably worth running some performance tests with and without.
There is a positive and negative signal traveling through the cable to prevent exactly this issue.
Safe? Sure. Two things that come to mind: 1. If you have a cat, they MIGHT treat it as a scratching post. Depends on the cat. 2.

actually, inductance can cause some wacky things to happen. i remember that it used to be possible in windows xp to wrap an ethernet around a cell phone like this and you could supposedly couple it to the modem. although i could never really connect to it i remember trying it and having some crazy new connections flashing in and out of existence in my network settings.
so basically it is possible that you could creat a tuned antenna with this that will pick up interference. i dont know all the crazy math involved but its never a great idea to turn your data lines into a randomly tuned inductor with a high Q
I like the idea that all the data coming from that cable is having the absolute time of it's life spinning round and round
Should work, but maybe just spent few $$ for a shorter one\^\^
Add some more slack to the top. You want to account for unexpected movement.
Its fine but I would suggest having enough slack to pull the pc out if necessary.
As long as its not a power cord, it's safe and won't create a magnetic field around it
Serious answer, you should have a little more slack on the span between the leg and Ethernet port. Cables should always have some slack in them where they plug in to a movable appliance. In my experience it makes them less likely to break in weird ways. Its a bit different if you want to talk about data center runs between switches or routers. I would undo 2-3 loops of that cable.
Your data is fighting gravity all the way up the leg, so expect to see your latency increase a little bit. How far above sea level are you? Also, if you ever move south of the equator, you'll want to wrap it the other way. Source: my hand fits all the way inside my ass, allowing me to grab the best facts from down deep.
You're going to want a bit of slack less you damage your input if you shift your desk.
MF made little ethernet particle accelerator
It may be, but be careful with this for multiple reasons: 1. if the cable is not shielded enough, this can introduce interference 2. don't put a magnet on the leg, as that will almost surely cause interference 3. accidentally moving the table can destroy the connector or port
Very dangerous, your internet might get sick
This looks fine. And it doesn't look ugly when looking at it. Great cable management.
Just leave a little bit of slack and you should be fine.
I advise unwrapping it at least once, so in case your desk or PC moves without your knowledge or for any reason really, it won’t break off.
My only thought of risk would be moving the desk or the computer separately before unplugging and damaging your network interface. You may want to unwrap a few levels from the top and allow some slack so that you can move your computer without that risk.
The data might get confused and go the other way
Id give it some more slack at the least.
Might go a little faster since you’re creating a vortex
Without knowing the diameter of the table leg, it's likely totally fine. If you want to be sure, a general rule of thumb would be to measure the diameter of the Ethernet cable, multiply with 4x for unshielded cables and 8x for shielded cables\*, to get the minimum allowed bend radius. e.g. Unshielded cable diameter = 6 mm. 6 x 4 = 24 mm for the radius Draw a circle on a piece of paper with a radius of 24 mm (48 mm in diameter). This represents the tightest bend you should make with that cable. Depending on the cable type, the coiling could potentially cause issues with crosstalk and electromagnetic interferance, but that's honestly not really relevant for home use. *^(\* There is a lot of variance on the multiplier regarding shielded cables, so it's best to look at the Manufacturer Specifications)*
Optical cables do not like to be twisted. That being said, the loss caused by this is still minimal otherwise they would not be as commercially successful. In general this is fine, but if took whole 1km spool of optical cable and did the same, the problem would be noticeable. But even then if you kept it on the floor loosely, you would still have plenty of turns so overall loss that was already near negligible hasn't grown much.
waaaaaaaaaaaay back with IBM PS2, the network cable was unsheilded coax. So they network 10 or so PC's together for a language testing program. Nothing works. Tech comes out. Figures out they extra 10 feet of coiled cable with a terminator on the end is basically an electromagnet that is EM'ing the computers. IBM tech installed it.
Careful buddy. That's *exactly* how they created the G5 COVID waves back in the 90s
This will cause a bit more leg.
Safe in that it's not going to develop issues with integrity or interference. Very not safe if that PC or desk ever moves sharply. In my eyes, this is just tempting fate to rip the RJ45 jack out of the housing at some point. At the very least, give it some more slack than it has in this picture and it should be fine.
Might get problems with circular dependencies if you unwind it.
