Vedclass · Answer

(C) When magnetic flux linked with a coil changes,an induced $emf$ is produced in it,and the induced current flows through the material. These induced currents are set up in the conductor in the form of closed loops. These currents resemble eddies or whirlpools and are known as $Eddy$ currents. These currents oppose the cause of their origin; therefore,due to $Eddy$ currents,a significant amount of energy is wasted in the form of heat energy. If the core of the transformer is laminated,the path for these currents is restricted,and their effect is minimized.
