Which mechanism generates current in an induction heater when a ferrous metal is placed within the magnetic field?

💡 Explanation

When ferrous metal is placed in a time-varying magnetic field, magnetic domain wall displacement occurs because the field forces realignment of magnetic domains, generating eddy currents within the material due to electromagnetic induction, leading to resistive heating. Therefore domain wall displacement causes heating, rather than piezoelectricity, Seebeck effects or quantum tunneling which rely on entirely different physical principles.
