JEE Main 2022 — Magnetic Properties of Matter Question with Solution

JEE Main 2022 (27 Jun Shift 1)

Question

The susceptibility of a paramagnetic material is 99. The permeability of the material in Wb/A-m, is [Permeability of free space μ0=4π×10-7 Wb/A-m]

Correct answer
A4π×10-5

Step-by-step explanation

Using the relation of magnetic susceptibility χ and relative permeabilityμr.

μr=1+χ=1+99=100

Magnetic permeability, μ=μ0μr

=4π×10-7×100

μ=4π×10-5
