The magnetic induction and intensity of the magnetising field in a sample of magnetic material are respectively `Wb//m^(2) and 2 xx 10 ^(3)` A/m. Find the value of magnetic susceptibility of the material. (Take,`mu _(0) = 4 pi xx 1 ^(-7) H//m)`

Explanation

Here, magnetic induction,
`B = ( pi)/(2) Wb// m ^(2)`
Magnetising field, `M = 2 xx 10 ^(3) A//m`
As we know, `B = m H …(i)`
`M = X _(m) H….(ii)`
