Vedclass · Answer

(D) In a transformer, energy is lost due to various factors, one of which is the formation of eddy currents in the iron core. When the magnetic flux through the core changes, it induces circulating currents (eddy currents) within the bulk of the core material, leading to significant heat dissipation ($I^2R$ loss). By laminating the core—using thin, insulated sheets of metal instead of a solid block—the path for these eddy currents is restricted. This increase in resistance significantly reduces the magnitude of the eddy currents, thereby minimizing the energy loss in the form of heat.
