If the magnetising field on a ferromagnetic material is increased, its permeability is

A

decreased

B

increased

C

is unaffected

D

may be increased or decreased

Text Solution

Verified by Experts

The correct Answer is:
A
Magnetic permeability of a ferromagnetic substance, `mu=B//H` or `muprop1/H`, where H is the magnetising field. If H increases then `mu` decreases.
