Rectangular pure permanent magnet

Pure permanent magnet

A rectangular pure permanent magnet is a material with a specific shape and magnetic properties. Its shape is rectangular, which gives it spatially clear boundaries and a stable structure. A pure permanent magnet means that it has the ability to spontaneously magnetize and maintain magnetism without the need for an external power source or other form of magnetization. The magnetic field of a rectangular pure permanent magnet is evenly distributed, and the magnetic lines of force form a closed loop inside the magnet, giving it unique advantages in certain applications. For example, in the fields of magnetic machinery, motors, sensors, etc., rectangular pure permanent magnets can be used as key components to provide stable and long-lasting magnetic support.
