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 B can also end but conductors cannot end them.
(c) lines of 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 B from the interior region.
