New and Improved Dipole Halbach Arrays
Our circular dipole halbach array is pre-assembled from 12 powerful, grade N48 neodymium magnets configured according to the picture on the left and enclosed in a protective nickel plated steel tube.
The magnets are arranged to work together to create a very intense "waterfall" of flux density passing through the inner diameter.
Inside of the array, the surface gauss is over 1.1 Tesla, while the average field density throughout the 1 inch diameter is 0.9 Tesla (or 9000 gauss). There is one North pole and one South pole on the inner diameter of the array.
Here is a technical article from Lawrence Livermore National Laboratory about a new electromechanical battery design that uses a dipole halbach array as a magnetic bearing, and a indepth paper on magnetic bearings that use dipole halbach arrays. And here is US Patent 5495221 - Dynamically stable magnetic suspension/bearing system that was filed in 1994 by Richard Post. You may also want to have a look at some of the other patents filed by Mr. Post.
