Question:

Case : Read the passage and answer the question(s).

When bulk pieces of conductors are subjected to changing magnetic flux, induced currents are produced in them. However, their flow patterns resemble swirling eddies in water. Consider a copper plate allowed to swing like a simple pendulum between the pole pieces of a strong magnet. It is found that the motion is damped and in a little while the plate comes to a halt in the magnetic field.

Why is the motion damped?

Options:

Energy losses due to eddy currents.

Hysteresis Loss

Frictional loss

None of the above

Correct Answer:

Energy losses due to eddy currents.

Explanation:

The eddy currents loss a lot of energy of the swinging plate causing it to eventually stop.
