- When a conductive material is subjected to a time-varying magnetic flux, eddy currents are generated in the conductor.
- These eddy currents circulate inside the conductor generating a magnetic field of opposite polarity as the applied magnetic field. The interaction of the two magnetic fields causes a force that resists the change in magnetic flux.
- However, due to the internal resistance of the conductive material, the eddy currents will be dissipated into heat and the force will die out. As the eddy currents are dissipated, energy is removed from the system, thus producing a damping effect.

Hey mate
The heating effect of eddy current is used for melting a metal in an induction furnace. Eddy currents of large magnitude are produced field. The changes in the magnetic field are so rapid that very large eddy currents are generated and heat produced is sufficient to melt quickly.
Hope it helps
