Vedclass · Answer

(C) Eddy currents are induced currents that circulate within the core of a transformer when it is subjected to a changing magnetic field,leading to energy loss in the form of heat.To minimize these losses,the core is constructed using thin,insulated sheets of metal stacked together,known as a laminated core.This lamination increases the electrical resistance of the path for eddy currents,thereby significantly reducing their magnitude and the associated energy dissipation.
