Answers
Answer 51 : A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.
Answer 52: Circular magnets have the north pole on the top, and they have the south on the bottom.
Answer 53: You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.
Answer 54: The magnet will rotate to face the north-south direction due to the magnetic force of attraction that takes place between the poles of the magnet and the magnetic poles of the earth.
Answer 55: List of Properties of Magnet:
- Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.
- Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.
- Directive Property – A freely suspended magnet always points in a north-south direction.
