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.

The small energy losses in transformers due to eddy currents can be reduced by
