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.

Event 1 : South pole is moved towards the coil.

Event 2 : North pole is moved away from the coil.

Options:

The current is developed in directions opposite to each other.

Lesser amount of EMF is developed in Event 2.

The galvanometer reading is opposite in both cases.

The current developed is in same direction.

Correct Answer:

The current developed is in same direction.

Explanation:

Current developed when South pole is moved towards the coil is opposite in direction to that developed when North pole is moved towards the coil. Similarly, current developed when South pole is moved towards the coil is same in direction to that developed when North pole is moved away from the coil.
