Write the relation between relative permeability and susceptibility.

Text Solution

Verified by Experts

In SI units,
`B=mu_(0)(H+I)`
Since `I=chi_(m)H`
`therefore" "B=mu_(0)(H+chi_(m)H)`
`B=mu_(0)H(1+chi_(m))`
Also `B=muH`
`therefore" "muH=mu_(0)H(1+chi_(m))`
or `mu=mu_(0)(1+chi_(m))`
or `mu/mu_(0)=1+chi_(m)`
or `mu_(r)=1+chi_(m)`
This is the required relation.
