Question

The magnetism of the magnet is due to:
A. The earth
B. Cosmic rays
C. The spin portion of the electrons
D. The pressure of a big magnet inside the earth

Answer 1

The force exerted by the magnets when they attract or repel is known as Magnetism. This force is due to the motion of the electric charges.

Complete step by step solution:
There is an unseen region around every magnet that will attract or repel any object. The unseen region around the magnet is called the Magnetic field. The spinning of the electrons causes magnetism. A strong magnetic force is produced when more electrons spin in the same direction. In every material, the magnetic field of the electron is void by contrasting a field of the magnet that is formed by the other pair of electrons.
It is clear from the above point; it is clear that the magnet’s magnetism is caused due to the spin motion of the electrons.
Therefore, option (C) is correct.

Additional information:
The magnetism property of the magnets depends on the materials and the direction of the spin of the electron. Based on the magnetism property the magnets are divided into three types.
Ferromagnets: the objects that have an iron that is greatly attracted by the magnets are known as Ferromagnets. This property is called ferromagnetism.
Paramagnets: the object that has aluminum that is weakly attracted by the magnets is known as Paramagnets. This property is called paramagnetism.
The magnets that weakly repel are known as the Diamagnets. Some magnets work only when the electricity passes through them. Our planet earth also has its electric field.

Note:
The orbital motion of the electrons can be changed by applying the orbital motion of the electrons. The orbital motion of the electrons cannot produce magnetism. We can use magnets in many ways. They are used in compasses and play an important role in magnetic resonance imagers ( MRI ).
