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

Options

A. electrostatic field lines can end on charges and conductors have free charges
B. lines of `vecB` can also end but conductors cannot end them
C. lines of `vecB` cannot end on any material and perfect shielding is not possible
D. shells of high permeability materials can be used to divert lines of `vecB` from the interior region

Answer

A, C, D

Explanation

2) 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.
