Abstract : A hollow cylindrical flux source (HCFS) is formed into a toroidal shape. A hollow toroid of magnetically neutral material is mounted in the central cavity of the toroidal flux source. The hollow toroid has a central coaxial toroidal cavity of given cross-section (e.g., rectangular). The toroid flux source and the hollow toroid are each equatorially split into two halves. When the two halves are brought into juxtaposition and a suspension of magnetic material is deposited in the coaxial toroidal cavity a permanent magnet toroidal ring will be fabricated.
