Abstract


A uniform magnetic field can be achieved with various simple structures of circular or square cross-sections. The main purpose of each of these is to create a larger volume of uniformly distributed magnetic field. The improvement of the desired zone homogeneity can be achieved by varying the design parameters of the coil and applying different optimization algorithms. In this paper, the Lee-Whiting circular coil system has been investigated considering the cross-section of the real conductor instead of the volumeless ideal conductor. The parameters of the coil were optimized to achieve a uniformly distributed magnetic field inside a spherical area and the desired total deviation rate along the centreline. The numerical calculations and the optimization procedure were performed on a simplified 2D axial symmetric model. The obtained results show that in the case of real conductors, the coil positions differ from the Lee-Whiting arrangement.
