Question

State whether true or false. A cylindrical magnet has only one pole.
(A)True
(B)False

Answer 1

Hint: Monopoles cannot exist in magnets since it violates Maxwell’s second law of magnetism that magnetic monopoles do not exist in nature. While studying electricity and magnetism although the two concepts are studied analogous to each other, the difference lies in the fact that single charges exist but single poles do not.

Complete answer:
There are various shapes of magnets available in the market. Magnets exist in the shape of bars, discs, cylinders, balls, etc. The cylindrical magnet is one such magnet shaped in the form of a cylinder whose poles usually lie along the height of the cylinder.
The cylindrical shape is designed so that due to the less surface area of the magnet, the magnet can produce high levels of magnetism. Hence, cylindrical magnets are very powerful. But besides that the behavior of the magnet remains the same. It consists of two poles, one North and the other South and they lie along the height of the cylindrical shape.
Thus, we can conclude that any piece of magnet necessarily has got two poles, North and South without any exception. Hence, the above statement that the cylindrical magnet has only one false is entirely false.

So the correct answer is option (B).

Additional Information:
It is impossible to get monopoles for any shape or size of a magnet. Even if we cut a magnet into 2 equivalent parts, both the parts will consist of two sets of N-S poles, that is each magnet will have a North pole and a South Pole.

Note:
While solving this question, it must be kept in mind that magnetic monopoles do not exist for any kind of magnet. Unlike charges which can exist in a single form, magnets do not follow the same property and magnetic poles always come in pairs.
