Hysteresis loops for two magnetic materials A and B are given below: These materials are used to make magnets for electric generators, transformer core and electromagnet core. Then it is proper to use :

Options

  1. AA for electromgnets and B for electric generators.
  2. BA for transformers and B for electric generators.
  3. CB for electromgnets and transformers.
  4. DA for electric generators and transformers

Correct answer

C. B for electromgnets and transformers.

Step-by-step solution

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