Essential difference between electrostatic shielding by a conducting shell and magneto static shielding is due to 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
Correct options are A) , C) and D) Conductors have free charge particles so the lines of force can be stopped by conductors gives shielding effect. As non-existence of mono pole magnetic field lines cannot be stopped or shield. Magnetic field lines are affected by magnetic material so can be replied by using a high permeability magnetic material to get the region of no magnetic field.
