Question
The adjacent diagram shows a small magnet placed near a solenoid. State whether the magnet is attracted or repelled, as the switch is pressed. Give a reason.

Solution
As the switch is pressed, the magnet will get repelled. The reason is that at the face of solenoid near the north pole of a magnet, the current flows in an anti-clockwise direction, so the face becomes north pole. The like poles repel, so the magnet is repelled.
