When a magnetic material is subjected to a magnetizing field of intensity 2 10^3 A/m , it produces a magnetization of 8 10^3 A/m inside the material. The absolute magnetic permeability of the material is : ( ₀ is the permeability of free space)

Step-by-step solution

The magnetic susceptibility is defined as the ratio of magnetization M to the magnetizing field intensity H . = M H Given: M = 8 10^3 A/m H = 2 10^3 A/m = 8 10^3 2 10^3 = 4 The relative magnetic permeability _r is related to susceptibility by: _r = 1 + _r = 1 + 4 = 5 The absolute magnetic permeability is given by: = ₀ _r = 5 ₀ Answer: 5 ₀
