Question

A loop is formed by connecting a coil of insulated copper wire to a galvanometer, and a magnet is:
A: Held stationary
B: Moved away along its axis
C: Moved along its axis
There will be an induced current in:

  1. A only
  2. A and B only
  3. B and C only
  4. A, B, and C

hintHint:

The current is formed when the relative motion is created between the magnet and the coil by moving the magnet away or along the axis.

The correct answer is: B and C only


    There will be an induced current in: B and C only
    • The electromagnetic current doesn't form when the coil and the magnet are stationary.
    • The current is formed only when there is a relative motion between the coil and the current.
    • The relative motion is formed when the magnet is moved away along its axis or moved along its axis.
