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.
