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 × 10 − 7 T m A − 1

Question

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 × 10 − 7 T m A − 1, 8.0 × 10 − 5 T m A − 1, 2.4 π × 10 − 5 T m A − 1, 2.4 π × 10 − 7 T m A − 1, 2.4 π × 10 − 4 T m A − 1

MARKS App · Accepted Answer

μ r = x m + 1 = 599 + 1 = 600 μ = μ o μ r = 4 π × 10 − 7 × 600 = 2 . 4 π × 10 − 4 Tm A
