An iron rod of susceptiblity 599 is subjected to a magnetising field of 1200 A/m . The permeability of material of rod is: (`mu_0 = 4 pi x 10^(-7) Tm A ^-1)

A

`8.0 xx 10^(-5) T mA^(-1)`

B

`2.4 pi xx 10^(-5) T mA^(-1)`

C

`2.4 pi xx 10^(-7) T mA^(-1)`

D

`2.4 pi xx 10^(-4) T mA^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`mu = X_(m) +1 = 599 +1 = 600`
`mu = 4pi xx 10^(-7) xx 600`
`=2.4 pi xx 10^(-4) T_(m)/A`
