You have two small metal bars, A and B, identical in size, shape, and appearance

Question

You have two small metal bars, A and B, identical in size, shape, and appearance. The bars exert mutually attractive forces on one another, and you realize that they are interacting magnetically. You know that one of the metal bars is a magnet, and one is a ferromagnet, but don't know which is which. Is it possible to determine, through observations with only the two bars themselves, which bar is a magnet and which is a ferromagnet? If so, describe the observations you would make, and how you would interpret those observations in reaching a conclusion. If it is not possible, explain why not.

Explanation / Answer

Ferromagnet is made of iron have strongest effects known as Ferromagnetism. A magnet attracts ferromagnet.

So if any iron piece of metal is moved to any of metal bars, if attraction occurs between two then that metal bar is magnet otherwise that metal bar is ferromagnet as ferromagnet will not able to attract that iron bar.
