GEOLOGY

Detailed explanation-1: -Magnetic field lines of force can pass through magnetic as well as non-magnetic substances. it can pass through paper, air, etc. It depends on the permeability of the substance whether is it permeable or nonpermeable. If the substance is permeable the magnetic field lines will pass through it easily.

Detailed explanation-2: -Yes, magnetism passes through all material with the exception of superconductors. This allows for magnetic levitation using superconductors. Some substances other than superconductors have varying permeability to magnetism and can bend magnetic fields, but none can block them.

Detailed explanation-3: -Magnetic fields can penetrate through water and plastic but the intensity would change in each case.

Detailed explanation-4: -Plastic cannot be magnetized either can it be attracted to a magnet. So, it is a non-magnetic material.

Detailed explanation-5: -Hence, Paper is not a magnetic material.
