Classification of Magnetic Materials
Types of Magnetic Materials. To study magnetic properties of magnetic materials, the material is usually placed in a uniform magnetic field and then the magnetic field is varied. There are three major kinds of magnetic behaviour: Diamagnetic materials . These materials are barely magnetised when placed in a magnetic field.
