Question 52: Magnetism and Matter

Question

The susceptibility of a paramagnetic material is 99. The permeability of the material in Wb/A-m, is :
[Permeability of free space $$\mu$$
0
= 4$$\pi$$ $$	imes$$ 10
$$-$$7
Wb/A-m]

Accepted Answer

$$\mu$$
r
= x  + 1
= 99 + 1 = 100
$$\Rightarrow$$ $$\mu$$ = $$\mu$$
