Block magnets are sometimes referred to as Bar Magnets when their length or width dimension exceeds their width or height. Some of these block magnet products are manufactured with a countersunk hole for easier attachment, however, square-shaped magnets are most often kept in place by means of a bracket or frame. As with Holding Pot magnets that use disc magnets, Block magnets can be enclosed on three sides with a rectangular metal case or ‘channel’ that multiplies the magnetic field strength and deflects the power to the uncovered base. The steel case protects the magnet and usually includes some holes to fix the magnet in position. These magnetic assemblies are used to hold and attract metal and are often seen in applications such as Latch Magnets, Tool Holders, Metal Removal devices and Metal Retrieval tools.
As with other magnet shapes, Block magnets are also used in the generation of electricity and to create mechanical movement in electric motors of all sizes. The Neodymium variety of Permanent magnets enable more power to be delivered by motors that are physically much smaller. This has had a significant influence on high-tech industries that utilise small electric motors such as Robotics, Vehicle Manufacturing and Aviation.
