Question

A specimen of iron of permeability `8 xx 10^(-3)` weber/A m is placed in a magnetic field of strength 160 A/m . Magnetic induction in this iron is
A. `0.8 Wb//m^(2)`
B. `5 xx 10^(-5) Wb//m^(2)`
C. `1.28 Wb//m^(2)`
D. `20 xx 10^(3) Wb//m^(2)`

Answer 1

`B = mu H`
`B = 8 xx 10^(-3) xx 160`
`= 1.28 Wb//m^(2)`
