Question

Consider electrostatic shielding by a conducting shell and magneto-static shielding. Now, choose the statement which does not show the coessential difference between them: (A) Electrostatic field lines can end on charges and conductors have free charges (B) Magnetic field lines can end but conductors cannot end them. (C) Lines of magnetic field cannot end on any material and perfect shielding is not possible. (D) Shells of high permeability materials can be used to divert lines of magnetic field from the interior region.

Magnetic field lines can end but conductors cannot end them.

Lines of magnetic field cannot end on any material and perfect shielding is not possible.

Shells of high permeability materials can be used to divert lines of magnetic field from the interior region.
