The susceptibility of annealed iron at saturation is 5500. Find the permeability of annealed iron at saturation.

A

`1.9 xx 10^(-3)`

B

`6.9 xx 10^(-3)`

C

`3.9 xx 10^(-3)`

D

`7.9 xx 10^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`x=5500, mu=?`
`rho=rho_(0)(1+x)`
`=4pixx10^(-7)xx(1+5500)`
`=6.9 xx10^(-3) Wb//Am`
