GEOLOGY

Detailed explanation-1: -Any magnet, regardless of its shape, has two ends called poles where the magnetic effect is strongest. If a fine thread suspends a magnet, it is found that one pole of the magnet will always point toward the north. This fact has been made used in navigation since the eleventh century.

Detailed explanation-2: -Experimentation shows that all magnets have two poles. If freely suspended, one pole will point toward the north. The two poles are thus named the north magnetic pole and the south magnetic pole (or more properly, north-seeking and south-seeking poles, for the attractions in those directions).

Detailed explanation-3: -Every magnet has both a north and a south pole. There are no magnets with only one pole (see magnetic monopoles).

Detailed explanation-4: -If you break a magnet into two pieces each piece will still have a north pole and a south pole. No matter how small the piece of magnet is, it will always have a north pole and a south pole. Despite some claims on the internet there is no such thing as a monopole magnet.

Detailed explanation-5: -Every magnet, regardless of its shape, has two poles. Magnetic Poles, cont. The poles received their names due to the way a magnet behaves in the Earth’s magnetic field. If a bar magnet is suspended so that it can move freely, it will rotate.
