A bar magnet is exactly as it sounds, it is a permanent magnet which has a magnetic length greater than its diameter or effective diameter for rectangular bar magnets. A bar magnet has a north and a south pole typically at opposite ends of the bar.
Bar magnets have been used in schools, universities and science projects for many years and now are extremely popular worldwide. Traditionally constructed using alnico material bar magnets are covered with two different colours that clearly indicate the north and south poles of the magnet. This makes them perfect for teaching young learners basic magnetic theory and principles.
Bar magnets are also commonly used in arts, crafts and manufacturing.
