Question
Figure shows a horizontal solenoid connected to a battery and a switch. A copper ring is placed on a frictionless track, the axis of the ring being along the axis of the solenoid. As the switch is closed, the ring will:
  1. Remain stationary.
  2. Move towards the solenoid.
  3. Move away from the solenoid.
  4. Move towards the solenoid or away from it depending on which terminal (positive or negative) of the battery is connected to the left end of the solenoid.
✓

Answer

  1. Move away from the solenoid.
Explanation:

$\text{e}=-\text{L}\frac{\text{di}}{\text{dt}}$
Current flow in the CKt is clock wise direction, due to Mutual Induction current flow in the loop anti clockwise direction. The net force applied on the loop in east direction. So we can say that the ring will move away from the solenoid.
