Materials which can be magnetized are called magnetic materials. When magnetized, such materials create a magnetic field around them. Some of the significant features of magnetic materials are given below:
Some materials are magnetized even below without the application of any magnetic field and become more magnetic then a week magnetic field is applied to such materials. Some materials show a magnetic response in a direction opposite to that of any extremely applied field's. This may be surprise to some, but all matter is magnetic. It is just that some materials are much more magnetic then others. The main distinction is that in some materials there is no collective interaction of atomic magnetic moments, where as in other materials there is a very strong interaction between atomic moments.
