User: How can you prove that repulsion is a sure test of magnetisation

Weegy: First, of course, the fact that two metal bars, when brought together in the correct orientation, repel each other tells us immediately that both have to be magnets. [ Both have to be magnets, because a simple iron bar would be attracted by either side of the magnet and not repelled. No other known force does that, EXCEPT perhaps two metal objects that we have charged up electrically with the same charge, i.e. both positive or both negative. Well, that throws a wrinkle into the test, does it? Of course, it is very hard to keep two metal bars charged. And if you touch them with anything, the charge is gone, and the repulsion won't happen again. This way you can differentiate your magnets. Second, let me say that I wouldn't state your question that categorically in the sense that "repulsion is the only sure test". We have three different macroscopic forces in our everyday world to deal with (I mean without going to the microscopic scale of nuclei of atoms, which feature two more forces): gravitation, electrostatic, and magnetic. ]

Repulsion is a sure test of magnetization because while both magnetized and unmagnetized materials can be attracted to a magnet, only two magnets with opposite poles repel each other.
