Halbach Array

What is the 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. It can be achieved more stronger magnetic field with fewer magnets.
 
Feature:
1. Magnetic field is on sinusoidal distribution, the more magnets in one pole, the more perfect sinusoidal distribution.
2. Enhance magnetic field.
 
Application:
1. Aluminum motor shell and axis(reducing motor weight)
2.Permanent magnet magnetic concentrator
3.Merchandise anti-theft buckle unlocker
4.External key board magnetic bar
5.Making uniform magnetic field with high magnetic field intensity(up to 1.5T)
6.High-strength magnetic sucker
7. Magnetic positioning device
8.New permanent magnet motor
