What are some different forms of magnetism?
How many forms of magnetism are there? I want to know more about the different forms of magnetism?

M$1 Answer
There are four forms of magnetism. Diamagnetism, paramagnetism, ferromagnetism and antiferromagnetism.
1. Paramagnetism - When magnetic force is applied then some materials shows magnetic behaviour. The material becomes a very weak temporary magnet. The north pole of the material is towards the south pole of the applied force. When magnetic force is withdrawn the material does not show any magnetic property. Paramagnetic materials are Sodium, Aluminium, Calcium, etc.
2. Diamagnetism - It is same as paramagnetism but the polarity of the material is just reverse. That means the north pole of the material is towards the north pole of the applied force. Bismuth is a diamagnetic material.
3. Ferromagnetism - This also same as paramagnetism. But the material becomes a strong magnet. If the magnetic force is applied for long time the material may become permanent magnet. Iron, Nickel and Cobalt is ferromagnetic material.
4. Antiferromagnetism - Naturally no material is anti ferromagnetic. But under some circumstances material may not show any response to magnetic force. Neither positive nor negative. This is called antiferromagnetism.
