Vedclass · Answer

(D) $1$. According to Faraday's law of induction,eddy currents are loops of electrical current induced within conductors by a changing magnetic field.$2$. When a solid metal core is used in a transformer,the changing magnetic flux induces large eddy currents,which lead to significant energy loss in the form of heat.$3$. By laminating the core (using thin,insulated sheets of metal),the path for these eddy currents is restricted,significantly reducing their magnitude.$4$. Therefore,the core is laminated to reduce eddy current losses and improve the overall efficiency of the device.
