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

Options

(a) decrease
(b) increase
(c) is unaffected
(d) may be increase or decrease

Correct Answer:

decrease

Explanation:

Magnetic permeability of substance, μ = B / H ⇒ μ ∝ 1/H

where, H is the magnetising or magnetic field strength.

So, the magnetising field of a ferromagnetic material is increasing thus its, permeability decreased.
