These materials are used to make magnets for electric generators, transformer core and electromagnet core. Then it is proper to use :

Quantrex Academy · Accepted Answer

Correct answer: C. B for electromgnets and transformers.

Since area of hysterics curve of (B) & is smaller it is suitable for electromagnet and transformer
