S is the surface of a lump of magnetic material .

A

Lines of `vec(B)` are necessarily continuous across S .

B

Some lines of `vec(B)` must be discontinuous across S .

C

Lines of `vec(H)` are necessarily continuous across S .

D

Some lines of `vec(H)` must be discontinuous across S .

Text Solution

Verified by Experts

The correct Answer is:
A, D
`vec(B)` is necessarily continuous across S . Outside the lump of magnetic material , `H=(B)/(mu_(0))` and inside the lump , `H=(B)/(mu)=(B)/(mu_(0)mu_(r))`
Thus lines of `vec(H)` cannot be continuous across S .,
