40x20mm Super Strong Neodymium Disc Magnet

Features

 

Surface treatment: zinc plating, nickel plating, nickel-copper-nickel plating, epoxy plating

 

Magnetization method: There are two magnetization methods for 40x20mm disc NdFeB magnets: axial magnetization and radial magnetization.

High magnetism: NdFeB magnets have the advantages of high remanence density, high coercivity, and high magnetic energy products. Even a relatively small 40x20mm disc NdFeB magnet can generate a strong magnetic field and strong suction and can absorb ferromagnetic materials several times or even dozens of times its weight.

 

Various magnetic performance levels: Its magnetic performance levels generally range from N25 to N52, and the common ones are N35, N40, N45, etc. The larger the number, the higher the magnetic energy product and the stronger the magnetism. For example, the maximum magnetic energy product of a 40x20mm disc NdFeB magnet of N45 grade is about 45MGOe, which can generate a stronger magnetic field than N35 grade.

 

 

Electronic equipment: in the computer hard disk, used to drive the rapid movement of the magnetic head and precise positioning, to achieve high-speed reading and writing of data; in cell phones, headphones and other small electronic equipment, can be used to achieve some of the functional modules of the fixed, inductive or magnetic coupling, etc., such as cell phone vibration motor in the magnet, headphones in the magnetic suction device.

Mechanical manufacturing: can be used to manufacture a variety of small motors, generators, etc., such as DC brushless motors, permanent magnet synchronous motors, etc., to improve the power density and efficiency of the motor; in automation equipment, as part of the sensor, used to detect the position, speed, displacement and other physical quantities, such as Hall sensors in the magnet.

Household goods: can be used to make refrigerator stickers, can be firmly adsorbed on the surface of the refrigerator, used to fix sticky notes, photos, and other items; can also be used in a number of magnetic storage boxes, jewelry boxes, etc., to facilitate the storage and access to the items.

Medical equipment: Medical equipment, such as small magnetic therapy devices, magnetic resonance imaging equipment, etc., can provide a stable magnetic field, used for the treatment of disease or medical imaging.
