Magnets come in a variety of shapes and sizes like disc, sphere, horseshoe and a number of other unique forms. Usually, bigger magnets are stronger, but now always. Small magnets can be improved to increase strength by using different materials. The shape of a magnet, however, can tell you a lot more than size. Each magnet’s shape has an influence how it is used. It determines how the magnetic field lines are arranged outside of the magnet as well as the strength of its pull. What are some of the common shapes of magnets and how are they used?
