Question

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

Options

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

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

• Lines of magentic 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.

Answer 1

Magnetic field lines can end but conductors cannot end them.
