Give the expression for total magnetic flux associated with the magnetic material subjected to the magnetising field.

Text Solution

Verified by Experts

`B = mu_(o) (H +M ).`
`B = mu_(o) (H+chi H).`
i.e., `" " B= mu_(o) H (1+chi ) "put" mu_(r) = 1 + chi`.
Hence `" " B = mu_(o)mu_(r)H = muH , ,mu_(o)H`= magnetic flux due to external field
`mu_(r)` H = magnetic flux due to internal field.
