Answer:
Eddy currents
Explanation:
When a magnetic flux linked across the coil changes, an induced emf is developed in the coil and hence the induced current is also developed in the coil.
If the induced current in the large conductor, the current is called eddy current. It produces the heating effect.
There are several applications of the eddy current.
(1) Electromagnetic brakes
(2) Induction furnace, etc.
To minimize the effect of eddy current we use choke coils, in which the core is made of laminated thin sheets.
