Bar Magnets are a universal rectangular shape for magnetic material and can be used for almost any application due to the variety of magnetic material available. For example, Neodymium Bar Magnets would suit an application requiring a stronger connection, and Ferrite Bar Magnets would suit an application requiring less magnetism but higher durability and lower cost. Bar magnets are often used as magnetic separators and water conditioners, but are the best option if you require a multipurpose magnet with maximum strength. AMF Magnetics Bar Magnets are used in a variety of different industries, such as manufacturing, advertising, film, and construction. Due to their endless different sizes and thicknesses there are infinite possibilities for these Bar Magnets!
