A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on the one side of the array while cancelling the field to near zero on the other side. We mainly make linear halbach arrays and Halbach Cylinder

Halbach Array

A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetisation.

Large and uniform magnetic field will be produced by halbacharray in a certain area, and its magnetic field can also exceed the remanence of the magnetic material itself.

Halbach array enhance magnetic field on one side, in the meanwhile keeping 

1. Materials

Magnet: Neodymium Magnet

Hardware part: 10# or 20# steel, martensitic stainless steel

2. Application

Linear Halbach arrays:

Such as the brushless AC motor, voice coils, magnetic drug targeting to high-tech applications such as wiggler magnets which are used in Particle acceleratorsand Free-electron lasers.

Halbach cylinder:

Such as brushless AC motors, magnetic couplings and high field cylinders. Both brushless motors and coupling devices use multipole field arrangements.
