Question

What is the main difference between a permanent magnet and a temporary magnet

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

In a temporary magnet, the atoms are not aligned unless and until they encounter a strong magnetic field. Therefore, domains of a temporary magnet easily lose alignment.

Whereas the atoms in a permanent magnet remain aligned even in the absence of external magnetic field. But when we provide heat to a permanent magnet then its atoms start to rearrange themselves and convert into temporary magnet.

Hence, we can conclude that out of the given options, the main difference between a permanent magnet and a temporary magnet is that the domains is a temporary magnet easily lose alignment but the domains in a permanent magnet keep their alignment.

Answer 2

The main difference between a permanent magnet and a temporary magnet is that the domains in a temporary magnet easily lose alignment but the domains in a permanent magnet keep their alignment.

Further Explanation:  

A magnet is an object that generates magnetic fields and therefore attracts magnetic materials such as nickel and iron.

Magnetic materials

• Magnetic materials are those materials that are attracted by a magnet, they include, iron, nickel and cobalt.  
• Magnetic materials can be used to make magnets through the process of magnetization.  

• Magnetic materials may be classified as paramagnetic materials and ferromagnetic materials.

1. Paramagnetic materials

• They are materials that are not strongly attracted by a magnet. They include, magnesium and aluminium.
• These materials can only be magnetized when placed on a very strong magnetic field.

     2. Ferromagnetic materials

• These are those materials that are strongly attracted by a magnet. They include iron, steel, cobalt, etc. Ferromagnetic materials may be soft or hard.

• Soft ferromagnetic materials are those materials that can be easily magnetized such as iron and its alloy.

1. They can also be easily demagnetized, therefore making them suitable for use in electromagnets, transformers, generators, and telephone receivers among other devices.
2. They are used to make temporary magnets.

• Hard ferromagnetic materials are those magnetic materials that are difficult to magnetize and demagnetize. They include, steel and cobalt. These materials are used to make permanent magnets and are suitable for use in devices such as speakers.

Non-magnetic materials

• Non-magnetic materials on the other hand are those materials that cannot be attracted by a magnet.
• They include, plastic, wood, rubber, water, etc. Non-magnetic materials cannot be used to make magnets.

Magnetization

• This is the process of making a magnetic object to obtain magnetism. Magnetization may be carried out using several methods, which include; electrical method, stroking, contact and also induction method.
