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:
- A only
- A and B only
- B and C only
- A, B, and C
Hint:
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.
