Question:Which of the following is not showing the essential difference between electrostatic shielding by a conducting shell and magnetostatic shielding?

1.Electrostatic field lines can end on charges and conductors have free charges.

2.Magnetic field lines can end but conductors cannot end them.

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

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