Question

A coil of insulated copper wire is connected to a galvanometer forming a loop and

a magnet is

A. held stationery

B. moved away along its axis

C. moved towards along its axis

There will be an induced current in

a) A only

b) A and B only

c) B and C only

d) A and C only​

Answer 1

Explanation:

The magnetic field around the coil remains constant. Thus, the magnetic field does not change. Hence, no current will be induced in the coil. Therefore, galvanometer will show no deflection.
