Halbach Magnet manufacturers tell you that a Halbach array is a special arrangement of permanent magnets that increases the magnetic field on one side of the array, while the field on the other side cancels out to near zero. This is achieved by having a spatially rotated magnetization pattern.

The way the permanent magnets (on the front; on the left, up, right, down) can continue indefinitely and have the same effect. The Halbach Magnet manufacturer tells you that the effect of this arrangement is roughly similar to that of many horseshoe magnets placed next to each other with their poles touching each other.
Halbach arrays are widely used in magnet rotors. Rare earth permanent magnet motor is a new type of permanent magnet rotor, which started in the early 1970s. Rare earth permanent magnet motors have a series of advantages such as small size, light weight, high efficiency and good characteristics. Halbach Magnet manufacturers tell you that it is widely used in aviation, aerospace, defense, equipment manufacturing, industrial and agricultural production, and daily life.
Halbach arrays can be made from sintered NdFeB magnets. NdFeB sintered magnet is a high performance rare earth magnet with high remanence, high coercivity, high energy product and high cost performance, easy to produce in various sizes.
Halbach Magnet manufacturers tell you that sintered NdFeB magnets are widely used in magnetic imaging of high performance stepper motors, DC motors, servo motors and linear motors, actuators, speakers, headphones, electronic instruments, switches, relays, medical and geophysical applications , holding systems, magnetic bearings, magnetic couplings, hard drives, magnetic separators, magnetic lifters, other magnetic tools, etc.
