Answer 1

Hysteresis loop with more area signifies a 'hard' ferromagnetic material and hysteresis loop with less area signifies a 'soft' ferromagnetic material. Hence, A is good for electromagnets and B is good for electric generators.

Answer 2

Hysteresis loop with more area signifies a 'hard' ferromagnetic material and hysteresis loop with less area signifies a 'soft' ferromagnetic material. Hence, A is good for electromagnets and B is good for electric generators.
