Question:
When a bar magnet is pushed towards the coil, along its axis, as shown in the figure, the galvanometer pointer deflects towards X. When this magnet is pulled away from the coil, the galvanometer pointer

Show Hint
When a magnet is moved towards or away from a coil, it causes a varying magnetic flux, which induces a current in the coil. The direction of the current alternates, causing oscillations in the galvanometer reading.

- oscillates
- deflects towards X
- deflects towards X'
- does not deflect

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
When a magnet is moved towards a coil, it induces a current in the coil due to the change in magnetic flux, which causes the galvanometer needle to deflect. Similarly, when the magnet is moved away, the direction of the induced current changes, leading to the opposite deflection in the galvanometer. This results in oscillations as the magnet is pushed back and forth due to the alternating increase and decrease in the magnetic flux.
Thus, the galvanometer pointer oscillates.
