Question

If you have a rectangular metal bar. How could you say whether it is a magnet or simply a magnetic material?

Answer 1

Answer:

Repulsion is a sure test for magnetism

Explanation:

We can tell if it is a magnet or not, by bringing another magnet. When you put it near the metal bar, if it attracts, then turn the metal bar around. If it attracts again, then that means the metal bar is a magnetic substance, but if it repels, then we can say, it is a magnet.
