A Halbach Array is a special configuration of magnets to maximise the magnetic field on one side whilst reducing it on the other.

In the ring form presented here, the magnetic lines are focussed inside the ring.

Halbach arrays are the cutting edge of new design in relation to generators, motors, magnetic bearings and many more applications.

These magnets are supplied in sets of 12 magnets and are NOT assembled in the ring arrangement for you.

You will need to assemble the magnets in the desired locations as described by the diagram below.

I recommend you will have a sufficient workshop and engineering knowledge to setup the ring arrangement.

The magnets are very powerful and you cant simply place them together with your hands, you WILL NEED specific tools to hold in place and secure these magnets.
