Abstract :
The authors present a method of field computation for permanent magnets designed to generate a uniform field in the region of interest. The computation technique is particularly suitable for magnetic structures used in magnetic resonance imaging. The method is applied to the design of yokeless, yoked, and hybrid prismatic magnetic structures. In particular, it is applied to the correction of the field inhomogeneity of open magnets by means of a modulation of the magnetic material and by the introduction of high-permeability materials
