HAHAHA this is gold. Coiling your cables (Ethernet or power) wont do anything real negative. Ethernet cable coiled RARELY creates induction as induction requires an ALTERNATING current. Ethernet is a dc voltage with 1's and 0's modulated onto it. Normally a square waveform. Hence no/extremely little induction can be created. On the other hand, with 240v POWER (AUS) coiling your power cables can create induction, but at <10a max running though it and less than 50+ coils the induction is so small its irreverent.

Going along with this, a very relevant topic is the co-location of power and Ethernet. Try and always keep AC power cables and data cables(Ethernet) separated by about 20cm to help reduce "AC noise" being imposed on the data lines.
Most, if not ALL, power companies impose a certain frequency onto the power line to tell "smart" meters when "peak" and "off peak" times are. Add that to the 50Hz that Aussie AC runs at and you can get a LOT of interference. BUT any CAT5e or greater cables have shielding for this exact reason.

Tnx fkr rly good explanation . I do some electronics , mainly dc but im not am expert. So i still need to hear others people opinions. Do we have here some good thread ablut electronics?
