Question

What are Eddy currents ? Describe the ways in which they are used to advantage.

Answer 1

When a conductor is placed in a charging magnetic field then the induced current developed there is called eddy current

APPLICATIONS

car speedometer

Induction furnace

Induction motors

Electro magnetic damping

Answer 2

Answer:

The eddy currents generated in the metals produce high temperatures sufficient to melt it. v Analogue energy meters : Concept of eddy currents is used in energy meters to record the consumption of electricity. Aluminium disc used in these meters get induced due to varying magnetic field.
