A permanent magnet causes repulsion with one pole when the poles are brought in turn near a suspended magnet. An unmagnetised magnet material would beattracted to both poles. Magnetism can work over a distance and magnets can exert a force (push or pull) on objects without making contact with them......

A magnet can attract any piece of iron, but it doesn't make the piece of iron a magnet.
However, when two like poles are brought together they will repel each other. Iron cannot repel a magnet.
Hence repulsion is the true test of magnetism.
