QJEEM22Ph9cc2: JEE Main 2022 Physics - Class 12 JEEM22Ph9cc2 Solution: The susceptibility of a paramagnetic material is 99. The…

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

[Permeability of free space μ\mu 0 = 4 π\pi ×\times 10 −- 7 Wb/A-m]

Multiple Choice Options

  • A 4 π\pi ×\times 10 −- 7
  • B 4 π\pi ×\times 10 −- 4
  • C 4 π\pi ×\times 10 −- 5
  • D 4 π\pi ×\times 10 −- 6

Step-by-Step Verified Solution

μ\mu r = x + 1

= 99 + 1 = 100

⇒\Rightarrow μ\mu = μ\mu r μ\mu 0 = 100 ×\times 4 μ\mu ×\times 10 −- 7 Wb/Am

= 4 μ\mu ×\times 10 −- 5 Wb/Am
