Soft and Hard Magnetic Materials - your electrical guide

Hard magnetic materials are hard to magnetize and hard to demagnetize. High values of both B s and H c characterize these materials and make them excellent permanent magnets. The former establishes the high induction field needed to strongly attract ferromagnetic materials; the latter prevents magnetic effects from being influenced or even destroyed by nearby magnets or external fields.

Hysteresis in magnetic materials

Hysteresis When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. It must be driven back to zero by a field in the opposite direction. If an alternating magnetic field is applied to the material, its magnetization will trace out a loop called a hysteresis loop.
