1. A magnet can attract the opposite pole of other magnet as well as the magnetic substance (iron cobalt nickel). When two magnets or magnetic objects with like poles face each other, a force of repulsion pushes them apart.
2. So, if a magnet attracts some, it cannot be concluded that the other object is a magnet. But if the magnet repels the object, then we can say that the other object is a magnet. Thus, repulsion is a sure test of magnetism.
