Question

The two ends of a magnet are called ……………...
A. Poles
B. Pens
C. Bars
D. Moments

Answer 1

Hint: Each of the magnets has two poles; north and south poles. Monopoles don't exist. A freely suspended magnet will align in the direction of poles of earth. North pole of the magnet towards the north pole of earth and south pole of the magnet in the direction of south pole of earth.

Complete step by step answer:
The ends of a magnet are known as poles. There is a north pole and south pole. If the magnet is freely moving then the north pole of the magnet points the north direction. So, the answer is option A.

Additional information:
The area surrounding the magnet in which magnetic force is exerted is known as magnetic field. The magnetic lines of force originate from the north pole to the south pole. The ends of the magnet where the magnetic force is concentrated are called magnetic poles. Each magnet has two poles. Monopoles don't exist. If we are playing with two magnets, we can see that like poles will attract each other, while opposite poles repel.
There are two types of magnets;
Natural magnets have low magnetic power and the examples are magnetite, loadstone etc.
Artificial magnets have strong magnetic power as well as they can form into any shapes.
The materials which can attract by a magnet are known as magnetic materials. Nickel, iron, steel, cobalt and some alloys are examples for magnetic materials.
A permanent magnet can alter the magnetic behaviour of a soft iron bar. If we placed a permanent magnet near to the soft iron bar, the soft iron will become an induced magnet. In this magnetic induction, opposite poles are inducing. So, it will look like two opposite poles are facing each other.
If we are placing two magnets with opposite pole alignment, the poles of magnets will repel. After some time, these magnets become weaker. We can prevent this weakening by using keepers. So, the keeper made by soft iron will become an induced magnet in this case.

Note: Magnetic field is a magnetic force experiencing region around a magnet. Since it is invisible, we need magnetic lines and poles to describe the direction and to study the magnetism. Two poles will be there for every magnet. Monopoles can’t exist. If a magnet breaks into two parts, then each part behaves like a magnet with another two poles.
