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

Question

If the magnetizing field on a ferromagnetic material is increased, its permeability (A) decreased (B) increased (C) is unaffected (D) may be increased or decreased

Tardigrade Admin · Accepted Answer

Magnetic permeability of substance μ=(B/H) ⇒ μ propto (1/H) where, H is the magnetizing or magnetic field. So, the magnetizing field on a ferromagnetic material is increasing, its permeability decreased.

Q. If the magnetizing field on a ferromagnetic material is increased, its permeability

decreased

increased

is unaffected

may be increased or decreased

Magnetic permeability of substance
$μ = \frac{B}{H} \Rightarrow μ \propto \frac{1}{H}$
where, $H$ is the magnetizing or magnetic field. So, the magnetizing field on a ferromagnetic material is increasing, its permeability decreased.

is unaffected

may be increased or decreased

Magnetic permeability of substance μ=HB​⇒μ∝H1​ where, H is the magnetizing or magnetic field. So, the magnetizing field on a ferromagnetic material is increasing, its permeability decreased.
