Question

How can you say that the strength of a magnet is maximum at its poles.

Answer 1

1. Magnetic field lines form a closed curve around a magnet.
2. They emerge from the north pole of the magnet and enter at the south pole of the magnet.
3. Magnetic field lines are more crowded at the poles compared to the center of the magnet.

.

Hence, the strength of the magnetic field at the north pole and the south pole of a magnet is maximum compared to the center of the magnet.
