Question

A coil of insulated copper wire is connected to a galvanometer. If a bar magnet is held stationary inside the coil then there will be no deflection in the galvanometer.

• A. True
• B. False

Answer 1

The correct option is A

True

Given, a magnet is kept stationary inside a coil of insulated copper wire. Since the magnet is kept stationary, the magnetic field remains unchanged. Due to this, there is no change in the number of field lines interacting with the coil and hence the current is zero and there will be no/zero deflection in the galvanometer.
