I've got a metal desk (actually a workbench) on which I have my computer, monitor, cable modem, a WiFi router, and some other devices. Rather than drill holes for hooks, I was thinking of getting some magnetic hooks to use along the back of the desk for cable management. Something like this: https://www.amazon.com/Magnetic-%EF%BC%ADaximum-Neodymium-Corrosion-Protection/dp/B0787Q54M1/ref=sr_1_4?dchild=1&keywords=magnetic+hooks&sr=8-4 One set of hooks for power cables, the other for USB and Ethernet so data is separated from power. Right now all the cables are on the floor behind the desk.
I am not at all familiar with electronics. The Ethernet and USB cables I have do not have any special shielding (the Ethernet cables are UTP). At the moment they are all on the floor, so they could potentially interfere with each other but I haven't noticed anything so far. The concern I have now is if I have them grouped together and then potentially running through magnetic fields from the hooks. Same thing for the power cables (I'm using surge suppressors for all power).
Am I being overly cautious/paranoid, or are there precautions I actually should take? Is using magnetic hooks for cable management okay?
I saw Running network cable near X-Ray equipment and this gives me hope, however magnetic fields and X-rays are not quite the same thing so I want to confirm my setup would be okay. Internet searching hasn't turned up anything that really applies to my situation, so I don't want to make false assumptions.
