Essential difference between electrostatic shielding by a conducting shell and magnetostatic shielding is due to

A

electrostatic field lines can end on charges and conductors have free charges

B

lines of `vec(B)` can also end but conductros cannot end them

C

lines of `vec(B)` cannot end on any material and perfect shielding is not possible

D

shells of high permeability materials can be used to divert lines of `vec(B)` from the interior region

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
Magnetic field lines are closed curge, i.e., they never have end points because such a point would indicate the presence of a non-existent monopole.
