Question

Write two examples of their useful applications .

Answer 1

Eddy currents are used Magnetic braking in trains, Electromagnetic damping, Induction furnace, Electric power meters.

Answer 2

Uses of Eddy Current:-

• Induction furnace:- The heating effect of eddy current is used for melting metal in induction furnace.
• Electric Brakes:- It is an efficient system of brakes employed in electric trains when the train is to be stopped, a strong magnetic field is applied to the rotating drum. This results in the generation of large eddy currents
