How to choose a ring magnet Before deciding which type of magnet to choose, it should be clear what role the magnet needs to play? Main function: move objects, fix objects or lift objects. The required magnet shape: ring magnet, round magnet, square magnet, tile magnet or special shape magnet. Ring magnets belong to a kind of magnets, such as magnet types: shape magnets: square magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, bar magnets, magnetic frame magnets, and attribute magnets : Samarium-cobalt magnets, neodymium-iron-boron magnets, ferrite magnets, alnico magnets, iron-chromium-cobalt magnets, industrial magnets: magnetic components, motor magnets, rubber magnets, powerful magnets, plastic magnets, etc. Magnets are divided into permanent magnets and soft irons. Permanent magnets are coupled with strong magnetism, so that the spin and electron angular momentum of the magnetic substance are arranged in a fixed direction. Soft magnetism is the addition of current (also a method of adding magnetic force) and other currents. Removing the soft iron will slowly lose its magnetism.

Ring magnets can be seen from the shape of magnets. There are many types of ring magnets in nature. Neodymium iron boron ring magnets are a typical ring magnet. Among the ring magnets, the neodymium iron boron ring Products such as magnets are very popular in people's lives and have broad application prospects!
