An iron rod of area ofcross-section `0.1m^(2)` is subjected to a magnetising field of `1000A//m`. Calculate the magnetic permeability of the iron rod.
[Magnetic susceotibility of iron `=59.9`, magneitc permeability of vaccum `=4pixx10^(-7)` S.I. unit]

Explanation

Given:
area of cross-section `(A)=0.1m^(2)`
magnetising field `(H)=1000A//m`
magnetic susceptibility of iron `(X_(m))`
`=5.9`
magnetic permeability of vacuum
`(mu_(0))=4pixx10^(-7)Wb//A-m`
Magnetic permeability `mu` is given by
`mu=mu_(0)(1+X-(m))`
`=4pixx10^(-7)(1+59.9)`
`=4pixx10^(-7)xx60.9`
`=765.29xx10^(-7)Wb//A-m`
