Certain metals or ferromagnetic alloys that demonstrate an attractive or repulsive force between these materials.
Any body that has the property of attracting iron. This may be a natural iron oxide or a mass of iron or steel that has this property given to it artificially. A piece of iron may be magnetized by passage of an electric current through an insulated wire wound around it.
A substance exhibiting magnetic characteristics, such as iron, holds the ability to generate a permanent magnetic field. On the other hand, an electromagnet manifests magnetic properties solely during the flow of electric current through its windings.
