Every iron atom in a ferromagnetic domain has a magnetic dipole moment equal to `9.27 xx 10^(-24) A m^(2)`. A ferromagetic domain in iron has the shape of a cube of side ` 1mum`. The maximum dipole moment occurs when all the dipoles are alligned. The molar mass of uiron is 55 g and its specific gravity is 7.9 .The magnetisation of the domain is .

A

`8.0 xx 10^(5) A//m`

B

`8.0 xx 10^(8) A//m`

C
