GEOLOGY

Detailed explanation-1: -Magnetic monopoles do not exist in nature. Even if we cut a magnet into two small parts, the new poles will always appear in pairs as shown in the diagram. Hence we cannot separate north and south poles of a magnet.

Detailed explanation-2: -When a bar magnet is cut into half both the halves will have a north pole and a south pole each. Magnets cannot have isolated poles. A new north pole and south pole will be formed at the edges where the bar magnet is cut as shown in the figure. So, the two halves will attract each other.

Detailed explanation-3: -Every magnet has both a north and a south pole. There are no magnets with only one pole (see magnetic monopoles). With an axially magnetized disc magnet, for example, you could write a big N and an S on either round face with a marker.

Detailed explanation-4: -Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

Detailed explanation-5: -Answer: Solution: (i) False; A magnet of any shape always has two poles: a north pole and south pole.
