  8(b) Classification of Magnetic Materials (5 Marks Answer) Magnetic materials are classified based on how they respond to a magnetic field. They are mainly divided into  three types . 1. Diamagnetic Materials Diamagnetic materials are substances that are  weakly repelled by a magnetic field . Properties: Magnetic susceptibility is  negative . Magnetic permeability is  less than 1 . They move from  strong magnetic field to weak magnetic field . Examples: Bismuth, Copper, Silver, Gold. 2. Paramagnetic Materials Paramagnetic materials are substances that are  weakly attracted by a magnetic field . Properties: Magnetic susceptibility is  small and positive . Magnetic permeability is  slightly greater than 1 . They move from  weak magnetic field to strong magnetic field . Examples: Aluminium, Platinum, Chromium. 3. Ferromagnetic Materials Ferromagnetic materials are substances that are  strongly attracted by a magnetic field . Properti...
