Question

Describe an activity to draw a magnetic field line outside a bar magnet from one pole to another pole.

Answer 1

1. Take a small compass and a bar magnet.
2. Place the bar magnet in a fixed position on the drawing board using an adhesive material.
3. Mark the boundary of the magnet.
4. Place the compass near the north pole of the magnet. The south pole of the needle points towards the north pole of the magnet.
5. Mark the ends of the needle.
6. By moving the needle, we can see that the north pole is occupied by the south pole of the needle.
7. By joining the points marked, a smooth curve is obtained.
