The following two methods are really the same idea:
1). Test against a known magnet. Observe whether there is an attraction or repulsion between them.
2). Hang the bar by a string from its mid-point. Observe whether it shows a tendency to align itself in a preferred direction.
Another method:
3). Observe whether the bar picks up paper clips. ---- If you have two bars and are told that one of them is a magnet but the other is not, and you are not allowed to use any other metal, string, etc. to determine which is which, see which one is attracted to the middle of the other bar. That one's the magnet.

∙ 13y agoA steel bar and a magnet both have countless magnetic domains within them. The difference is that in the magnet, a number of the magnetic domains are aligned. As they all "point" in the same direction, the magnet will have some overall or net magnetic field. It is a permanent magnet. In a steel bar, the magnetic domains are randomly arranged, and there will be no net or overall magnetic field.
