Motorcycle speedometer magnets originated in the 1970s. At first, Alnico2 D23*D13.5*3 was widely used. Later, with the development of the times, Alnico3 D23*D6*4 gradually replaced Alnico2 in order to save costs. They are both isotropic magnets. Speedometer magnets are usually not magnetized. They are magnetized after being installed in the movement and assembled to prevent […]

A pot magnet is a permanent magnet encased in a steel shell, essentially creating a container or “pot” for the magnet. This shell amplifies the magnet’s pulling force and protects the magnet from chipping or cracking. Here are some key points about pot magnets: Stronger magnetic force: The steel shell concentrates the magnet’s magnetic field […]

Magnetic chess is not a specific game but a term for chess that uses magnets. These sets can be used to play two main types of games: 1. Magnetic Pinball (Takeout): This is a simpler game sometimes aimed at younger children. Players take turns placing magnetic balls on the board. If a player’s magnetic ball […]

Small DC motor: The curved shape concentrates the magnetic field, making it suitable for small DC motors used in toys, hobby projects, or some internal components in electronics. Magnetic stirrers: Rotating ferrite arc magnets can be used to generate rotating magnetic fields to stir liquids in closed environments, aiding in small-scale mixing tasks in laboratories […]

Here’s how to identify the Alnico magnets mentioned above: Visual clues: Luster: Alnico magnets usually have a metallic luster, while ferrites (ceramics) are usually dark gray and lack luster. Neodymium (NdFeB) magnets can also have a shiny appearance, but it may be a brighter silver or gray. Samarium cobalt magnets usually have a dark gray […]
