Question

How many number of new magnets will be formed, when a bar magnet is cut into 15 pieces?​

Answer 1

Explanation:

a) If a bar magnet is hung by a thread tied at its centre, its north pole becomes steady in the direction of the north Pole of the earth. (b) If a bar magnet is cut into equal pieces by cutting it at right angles to its axis at two places, 3 bar magnets are formed, and a total of 6 poles are formed.
