Question

An iron rod is subjected to a magnetising field of 1200 Am^-1 .The susceptibility of iron is 599. Find the permeability and the magnetic field produced. 

Answer 1

Given: H = 1200 Am^-1, `chi` = 599

Permeability, `mu=mu_0(1+chi)`

`=4pixx10^-7xx(1+599)`

`mu=7.536xx10^-4T  mA^-1`

Magnetic field, `B = muH`

`=7.536xx10^-4xx1200`

`B = 0.904  T`
