An iron rod of susceptibility $599$ is subjected to a magnetising field of $1200 A m^{- 1}$ . The permeability of the material of the rod is:
$(μ_{0} = 4 π \times 10^{- 7} T m A^{- 1})$ NEET 2020 (Phase 1)

Options:

Answer:

Solution:

$μ_{r} = x_{m} + 1 = 599 + 1 = 600$

$μ = μ_{o} μ_{r} = 4 π \times 10^{- 7} \times 600$

$= 2.4 π \times 10^{- 4} \frac{Tm}{A}$
