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 :
A
` A` for transformers and `B` for electric generators.
B
`B` for electromagnets and transformers.
C
`A` for electric generators and transformers
D
`A` for electromagnets and `B` for electric generators.
Text Solution
Verified by Experts
The correct Answer is:
B
Graph `[A]` is a for material ued for making permanent magnets ( high coercivity) Graph `[B]` is for making electromagnets and transformers.
