Re: [Vo]:Heating of iron rod at proximity of spinning magnet

Iron / steel has much higher resistance than copper (so-called resistance wire for domestic heating elements is usually steel). Resistance heating due to eddy currents is the only source of heat in induction; domain flips are fueled by ambient phonon exchanges (the principle exploit in MCE

Magnetic materials have hysteresis in the B-H curve that causes work to be done when the magnetic field changes. On Sun, Feb 28, 2016 at 11:34 AM, H Ucar wrote: > I observed dramatic heating of iron/steel rods of 2-4 mm diameter at 5 to > 10 mm distance to spinning Nd magnet
