Magnetic & Non-Magnetic Substances

Materials that are attracted by a magnet are known as magnetic substances . e.g. iron, steel, nickel, cobalt, manganese, alloy of metals. They are also called ferromagnetic substances.

A ferromagnetic material has a high and positive magnetic susceptibility. The magnetic susceptibility of a ferromagnetic material is a measure of how strongly it’s attracted to a magnetic field. Ferromagnetic materials have a high susceptibility because they’re made up of atomic magnets that can be easily lined up by an external field.

Materials that are not attracted by magnets are called non-magnetic substances . e.g.
