In the above diagram, a strong bar magnet is moving towards solenoid-2 from solenoid-1. The direction of induced current in solenoid-1 and that in solenoid-2, respectively, are through the directions:

  1. AB and CD
  2. BA and DC
  3. AB and DC
  4. BA and CD

Correct answer · Option 3

AB and DC

Explanation

By Lenz's law, solenoid-1 opposes the receding North pole by producing a South pole on its right face (current AB). Solenoid-2 opposes the approaching North pole by forming a North pole on its left face (current DC).
