Eddy Currents :
Eddy currents are the currents induced in the body of a conductor when the amount of magnetic   flux linked with it changes. The experimental concept was given by Focault and hence they are also named as Focault currents.
 

Applications of eddy currents

(i)    Induction furnace (heating effect of eddy current)

(ii)   Dead-beat galvanometer (electromagnetic damping)

(iii)  Electric brakes

(iv) Diathermy ( Strong 50 MHz A.C. passed through human body, also called deep heat treatment )

(v)  Induction motor

(vi) Car-speedometer
