FeCrCo (iron-chromium-cobalt) and AlNiCo (aluminum-nickel-cobalt) magnets are two distinct types of permanent magnets, each with unique properties and applications. Here are the main differences: Composition: FeCrCo: Primarily made of iron, chromium, and cobalt, with possible additions of other elements like nickel or copper to enhance specific properties. AlNiCo: Composed mainly of aluminum, nickel, and cobalt, […]

What is Electropermanent magnet？ An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by pulses of current in a winding of wire around the magnet portion. The magnet consists of two parts, one of a “hard” (high coercivity) magnetic material and […]

Magnets can be classified into two main categories based on their magnetic properties: isotropic and anisotropic. Isotropic Magnets Isotropic magnets have a random direction of magnetization throughout the material. This means that the tiny magnetic domains within the magnet are not aligned in any particular direction. Because of the random orientation, isotropic magnets tend to […]

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 […]

Description A magnetic pump consists of three parts: a pump, a magnetic actuator, and an electric motor. The key component of the magnetic actuator is composed of an external magnetic rotor, an internal magnetic rotor, and a nonmagnetic isolation sleeve. When the electric motor drives the outer magnetic rotor to rotate, the magnetic field can […]
