| Soft Magnetic Materials |
Hard Magnetic Materials |
| Soft magnetic materials are those materials that have a smaller area enclosed by their Hysteresis loop |
Hard magnetic materials are those materials that have a Larger area enclosed by their Hysteresis loop |
| They have low remnant magnetization |
They have high remnant magnetization |
| They have low coercivity |
They have high coercivity |
| They have high initial permeability |
They have low initial permeability |
| Hysteresis loss is less |
Hysteresis loss is higher |
| Eddy's current loss is less |
Eddy's current loss is more for metallic types and low for ceramic types. |
| Used in transformer cores, motors, generators, electromagnets, etc. |
Used in making permanent magnets, magnetic separators, magnetic detectors, speakers, microphones, etc. |
| Example: Iron-silicon alloys, Nickel-iron alloy, and iron. |
Example: Conventional metal magnets, such as alnico and alcomax, Ferrites, Cobalt platinum, Rare earth cobalt, Neodymium iron boron. |
