Abstract
A novel method of producing a highly uniform magnetic field by means of permanently magnetized wedges is presented. The method uses a pair of central wedges to generate a primary field and pairs of compensating blocks to improve the field uniformity. The geometry of the central wedges and compensating blocks are determined by an analytic procedure. Using the method, magnetic structures can be designed that allow access to the uniform field over a solid angle of approximately 2π steradians
