S is the surface of a lump of magnetic material .

A

Lines of `vecB` are necessarily continuous across S.

B

Some lines of `vecB` must be discontinuous across S.

C

Lines of `vecH` are necessarily continuous across S.

D

Lines of `vecH` cannot all be continuous across S.

Text Solution

Verified by Experts

The correct Answer is:
A, D
The lines of `vecB` do not have a discontinuity upon a transition through the interface while the `vecH` lines have a dinuity due to surface magnetisation currents.
