1.What is Halbach Array magnet
Halbach array is a kind of specialized and interesting arrangement of permanent magnet which invented by Klaus Halbach on 1979. The array was originally designed to help particle accelerators to focus beams on Lawrence Berkely National Laboratory. The magnetization direction of two adjacent magnets in the array differs on a certain angle, hence caused asymmetrical distribution of the magnetic field.

2.Characteristics of Halbach Array magnet
1. 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.
2. Halbach array enhance magnetic field on one side, in the meanwhile keeping the field to very low level on the other side.

3.Halbach array have excellent performance when a “gap” is present.
4.Magneticfield of halbach array exhibit sine distribution, and drastically reduces harmonic waves.

5.Effective increase power.
6.Excellent magnetic shielding effect, then obtain outstanding structural
3.Classification of Halbach Arraymagnet
The halbach array mainly includes straight-type halbach array and circular-type halbach array according to geometry. Circular-type halhach array can be further divided into O.D. iteration and I.D. iteration on the basis of the arrangement of the permanent magnet. Different directions and strength will be yielded by different magnet configuration.

4.Applications of Halbach Array magnet
The application includes:
1.Simple fixture and holding.
2.Rotors for DC motor, linear motor, servo motor, magnetic coupling and power generator.
3.Magnetic levitations.
4.High energy physics area, such as the particleaccelerator, free-electron laser device, synchrotron radiation facility, and magnetic lens.
5.Medical

It should be noted that halbach array is extremely difficult to assemble. The magnets need to be assembled under the magnetized state, that it, manufactures should combated the force between repelling magnets. Magnets in halbach array also more susceptible to be demagnetized.

7.Shipping Details:
A: We have a discount price with Fedex and DHL. So if the weight is under 100Kg, you can those two shipping companies. But you can also choose TNT, UPS or any other shipping companies if you like. We'll use iron boxes to shield the magnetics force for air shipping.
B: When the weight is over 100Kg,we think sea shipping is more reasonable. We have our own forwarder, you can also entrust your own forwarder.
C: Anyway, we'll respect your choices.
