The susceptibility of a paramagnetic material is 99 . The permeability of the material in Wb / A - m , is [Permeability of free space μ 0 = 4 π × 10 - 7 Wb / A - m ]

Question

TestHub · Accepted Answer

Using the relation of magnetic susceptibility χ and relative permeability μ r . μ r = 1 + χ = 1 + 99 = 100 Magnetic permeability, μ = μ 0 μ r = 4 π × 10 - 7 × 100 μ = 4 π × 10 - 5
