What happens to a Steele bar when you move it closer to a magnet?

When a steel bar is moved closer to a magnet, it becomes magnetized due to the alignment of its internal magnetic domains. The magnetic field of the magnet causes these domains, which are normally random, to align in the direction of the magnetic field. As a result, the steel bar itself starts to exhibit magnetic properties and can attract ferromagnetic materials or other magnets. If the bar is removed from the magnetic field, it may retain some of its magnetization, depending on the type of steel and the strength of the magnet.
