Write the Properties of magnet.

Explanation

(i) A freely suspended bar magnet will always point along the north - south direction.
(ii) A magnet attracts another magnet or magnetic substances towards itself . The attractive force is maximum near the end of the bar magnet. When a bar magnet is dipped into iron filling, they cling to the ends of the magnet.
(iii) When a magnet is broken into pieces, each piece behaves like a magnet with poles at its ends.
(iv) Two poles of magnet have pole strength equal to one another.
(v) The length of the bar magnet is called geometrical length and the length between two magnetic poles in a bar magnet is called magnetic length . Magnetic length is always slightly smaller than geometrical length.
