Question

State whether true or false
Unlike poles of a magnet repel each other
(A) True
(B) False

Answer 1

Hint:Magnet has two poles- the north pole and the south pole. Monopoles of a magnet cannot exist, unlike charges. Magnetic poles interact with each other just like how electric charges interact. Magnetic force is given by Biotsavart law.

Complete step by step answer:
There are two poles in a magnet and each pole exert force on another pole. This force is directly proportional to the magnitude of pole strength and is inversely proportional to the square of the distance between them. Just like electric force magnetic force lets it to the cause that like poles attract each other and unlike poles repels each other. Thus, the given statement that unlike poles repel each other is false. Hence, the correct option is (B)

Additional information: Magnets can be natural as well as artificial. Natural magnets are bar magnets and there are some stones found in nature which display magnetic properties. Artificial magnets examples include electromagnets and solenoids. The difference between natural and artificial magnets is that in the case of artificial magnets they tend to behave magnets till time electric current is flowing through them and when the current stops their magnetic nature disappears.

Note:We can observe how poles behave with each other. If we take two bar magnets with N and S mentioned on them and when we bring North pole in contact with the north pole of another magnet it repels and when we bring in N pole with S pole of another magnet they attract. Attraction and repulsion is a test of magnetism.
