Question

Relative permeability of a substance is 0.075. Its magnetic susceptibility is (A) 0.925
(B) -0.925
(C) 1.075
(D) -1.075

Answer 1

The magnetic susceptibility of a dimension is the proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field.

If the relative permeability of a matter is 0.075 then there magnetic susceptibility will be,

μ divided by μ0 = 1 + Xm

Here x – is chi

0.075 – 1 = Xm

Xm = - 0.925
