Sr.No.	Soft Magnetic Materials	Hard Magnetic Materials
1	Soft magnetic materials are those materials which have a smaller area enclosed by their Hysteresis loop	Hard magnetic materials are those materials which have a Larger area enclosed by their Hysteresis loop
2	They have low remnant magnetization	They have high remnant magnetization
3	They have low coercivity	They have high coercivity
4	They have high initial permeability	They have low initial permeability
5	Hysteresis loss is less	Hysteresis loss is higher
6	Eddy current loss is less	Eddy current loss is more for metallic types and low for ceramic types.
7	Used in transformer cores, motors, generators, electromagnets, etc.	Used in making permanent magnets, magnetic separators, magnetic detectors, speakers, microphones, etc.
