Or put simply, its a magnetic force that is generated when current carrying cables pass through a ferrous material. A transformer makes good use of this, whilst live and neutral conductors in an installation entering a metal cabinet through different holes is a bad use of this ( I have seen a 6x6 trunking glowing red).

eddy currents are the reason that transformer steel blocks are made up of laminates, to minimise the eddy currents.

That's why the 70mm + tails outa CT metering enclosures pass through a paxolin insulating cover rather than metal otherwise there would be a moulten pool of metal right rapid surrounding the tails! :eek:
