Answer
In terms of hysteresis behavior:
A hard magnetic material has a high remanence, a high coercivity, a high saturation flux density, high hysteresis energy losses and a low initial permeability.
A soft magnetic material has a high initial permeability, a low coercivity, and low hysteresis energy losses.
In terms of applications:
Hard magnetic materials are utilized for permanent magnets.
Soft magnetic materials are used in devices that are subjected to alternating magnetic fields such as transformer cores, generators, motors, and magnetic amplifier devices.
