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.

What does the change in flux produce?

All of the above

Eddy currents produce electricity in the bulk matter which gives rise to magnetism.
