Question

An iron bar A is attracted by a magnet on one end but repelled at the other end. Another iron bar B is attracted by the magnet on both its ends. Which of the two iron bars A or B, could be a magnet ? Give reasons.

Answer 1

Answer:

The iron bar A is a magnet.

EXPLANATION

Because of the attraction and repulsion property of magnets. It states that :

When the poles of two magnets are brought close to each other, they exert force on each other. Like poles repel and unlike poles attract. i.e The north pole of one magnet repels the north pole of the other magnet similarly the South Pole of a magnet repel the South Pole of another magnet where as the South Pole of one magnet attracts the north pole of another magnet similarly the north pole of one magnet attracts the South Pole of another magnet.
