what are the types of magnetic materials?how many types are there?explain in detail?
It would be pretty extensive to explain in full. It really depends at what level you want to describe magnetic behaviour. The best source for what i studied with is a book published by the Oxford University Press called Magnetism in Condensed Matter written by Stephen Blundell. It is brilliantly written and very clear and concise. This is graduate/masters level. Other than that i'm sure i can reel off some basic desciptions if you don't need something so intensive. Good luck :-)
