Solution

The correct option is C

The end A of the solenoid behave as north pole


Explanation:

  1. It occurs in accordance with Lenz's law. To oppose the magnet's motion, end A becomes the north pole.
  2. According to Lenz's law, In order to ensure that the original flux is maintained through the loop when current flows in it.
  3. The induced electromotive force with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop.

Hence, Option(C) is correct.
