Question:

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

Consider a coil C1 connected to galvanometer as shown. A magnet is placed next to the coil with its North pole facing near the coil and South facing away from the coil. The magnet is then moved towards the coil.

In context to this, answer the following question.

If the bar magnet is brought close to the coil and then stopped, what happens after it is stopped?

Options:

The current remains constant.

The EMF continues to be in the coil.

The galvanometer reading stays deflected.

None of these.

Correct Answer:

None of these.

Explanation:

When the bar magnet is stopped, there is no EMF developed in the coil  and consequently no current flows. The galvanometer reading shows no deflection at all.
