Coercive force of magnet
WebA good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it. The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materials. When a ferromagnetic material is magnetized in one direction, it ...
