State three differences between the temporary and permanent magnets.

Hint: In order to answer the above question, we will understand the term magnets. We will see that magnets are divided into two categories. We will understand both the types of magnets and will state the differentiation between them.

Complete answer:
As we see in our lives, magnetic fields exist in materials with magnetic properties. Atoms are the building blocks of all objects in the universe. At the core of each atom is a nucleus. The nucleus is surrounded by tiny particles called electrons. The electrons are surrounded by magnetic fields as a result of this process. As electrons spin in the same direction, magnetism occurs. When all of the electrons' magnetic forces combine, the material becomes one large magnet.

Based on the directions of spins of a magnet, they are categorized into two types:
(A) Permanent magnets
(B) Temporary magnets
A standard steel nail's magnetic field is insufficient to attract a metal paper clip.Magnetization, on the other hand, may strengthen the magnetic field of a steel nail. Simply by placing a strong permanent magnet next to a steel nail, the nail can gain a stronger magnetic field and act as a temporary magnet. The nail is referred to as a temporary magnet because it loses its magnetic field power that attracts the paper clip once the permanent magnet is removed.

The difference between the temporary and a permanent magnet is given in the following table.



Note: It is important to note that when a material is placed in a strong magnetic field, it possesses magnetic properties and the material is known as a temporary magnet. This process is called magnetization. When the magnetic field is removed, the material loses its magnetic properties. But the important thing to notice is that after removing the field, the material does not lose the magnetic properties immediately. It takes some time for all the electrons to align themselves to their original conditions and this is known as magnetic retentivity.
