Explanation:

Eddy currents are current circles formed over captain shells due to changing glamorous flux. They're useful in induction heating, levitating, electromagnetic damping, and electromagnetic retardation. They can be minimized by adding places on the captain's face &laminating. When a thick metallic piece is placed in a time-varying glamorous field, the glamorous flux linked with the plate changes, and the convinced currents are set up in the captain, these currents are called eddy currents. These currents are occasionally so strong, that the metallic plate becomes red hot.
