Question

How to find directions with a magnet?

Answer 1

1. Tie a piece of thread to the center of a bar magnet and suspend it freely.
2. Note the direction in which the magnet stops.
3. Draw a line on a cardboard sheet along the direction in which the bar magnet stops, (ie., a line parallel to the bar magnet)
4. Turn the magnet gently and let it come to stop again.
5. Repeat it three or four times. The magnet always comes to rest in a north-south direction.
