(a) Difine the term magnetic susceptibility and write its relative in terms of relative magnetic permeability. (b) Two magnetic materials A and B have relative magnetic permeabilities of 0.96 and 500. Identify the magnetic materials A and B.

(a) For definition of magnetic susceptibility, see Point Number 23 under the heading “Chapter At A Glance”.
Magnetic susceptibility X = u^r – 1, where u^r is the relative permeability of given material.
(b) The magnetic materials A, whose relative permeability is 0.96, is a diamagnetic substance.
The magnetic materials B, whose relative permeability is 500, is a feroomagnetic substance.

    1. Magnetic susceptibility χ = μ r −1, where μ r is the relative permeability. Material A (μ r =0.96) is diamagnetic due to χ < 0, while material B (μ r = 500) is ferromagnetic with strong alignment (χ ≫1).
