Question

tell me about eddy current

Answer 1

Have you seen a speedometer inside your vehicle? In the speedometer, a small magnet is connected to the main shaft of the vehicle. According to the speed of the vehicle it rotates. Due to the effects of the eddy currents the motion of the rotating is opposed and the pointer gets deflected through a certain angle. The pointer attached to the calibrated scale indicates the speed of the vehicle.

Induced electromotive force is produced in the coil when there is a change in the magnetic flux linked with that coil. Eddy currents are named so because the current looks like eddies or whirlpools. When a conductor is placed in the changing magnetic field, the induced current in the conductor is termed as Eddy currents

Answer 2

Answer:

Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field.
