Question
A coil of insulated copper wire is connected to a galvanometer forming a loop and a magnet is:
I: Held stationary
II: Moved away along its axis
III: Moved towards along its axis
There will be an induced current in:
- I only
- I and II only
- II and III only
- I, II and III
Hint:
The induced current forms in a galvanometer when the magnet is moved away or pushed towards its axis.
The correct answer is: II and III only
There will be an induced current in: II and III only
- An induced current forms in a galvanometer where the magnet is getting into contact with the region of the wire.
- When a coil is insulated with copper wire connected to a galvanometer, the induced current forms when the magnet is moved away or towards the axis.
- The induced current will not be formed when the magnet is stationary and is not moved to the axis.
