This arc segment is designed so that 12 of them will combine to form a ring of 4" od x 2" id. This arc is magnetized through the radius, with the north pole on the outer face. Twelve of these can be forced together and contained in a ring, to form a pseudo radially magnetized ring with the north pole around the outer circumference.
These can also be combined with our AY0X030-C
to form a circular Halbach array.
