Question

Hysteresis loops for two magnetic materials A and B are given below:

• A. A for electromagnets and B for electric generators
• B. A for transformers and B for electric generators
• C. B for electromagnets and transformers
• D. A for electric generators and transformers

Answer 1

The correct option is C

B for electromagnets and transformers

For electromagnets, electric generators and transformers energy loss should be less. Hence, (B) should be used
