A magnetic field strength (H) 3xx10^(3) ...

A magnetic field strength `(H) 3xx10^(3) Am^(-1)` produces a magnetic field of induction `(B)` of `12piT` in an iron rod. Find the relative permeability of iron ?

Text Solution

Verified by Experts

`mu=B/H=(12pi)/(3xx10^(3))=4pixx10^(-3)`
`thereforemu_(r)=mu/mu_(0)=(4pixx10^(-3))/(4pixx10^(-7))=10^(4)`
