Bullet Magnets

What is Bullet Magnets ? Bullet magnets also known as magnetic bullet separators, are a powerful and effective method for removing ferrous metal contaminants from dry, granular or powdered products. They are used in a variety of industries including food, pharmaceutical and chemical to ensure the purity and quality of the product. It can also […]

Alnico Speedometer Magnets

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 […]

What is a pot magnet?

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 […]

Application of ferrite arc magnets

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 […]

How to identify Alnico magnets?

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 […]
