Question

The susceptibility of a paramagnetic material is 99. The permeability of the material in Wb/A-m is ______.

[permeability of the free space μ₀ = 4π × 10^-7 Wb/A - m]

Options

• 4π × 10^-7 

• 4π × 10^-4 

• 4π × 10^-5 

• 4π × 10^-6 

Answer 1

The susceptibility of a paramagnetic material is 99. The permeability of the material in Wb/A-m is 4π × 10^-5.

Explanation:

μ_r = 1 + χ = 1 + 99 = 100

μ = μ₀μ_r = μ₀ × 100 = 4π × 10^-7 × 100

4π × 10^-5
