Heating From Magnetic Eddy Currents

Most recent answer: 11/12/2014

we know that magnet wen brought near a coil develops a electric field and wen electricity is generated then its heating effect also will be generated... so does magnet produces heating effect?

When the magnet moves near the coil, or the coil moves near the magnet, currents are generated in the coil. These do cause heating, just as you say. The magnet won't cause any heating if it's at rest with respect to the coil.
