Abstract :
The magnetic field of bitter type rectangular coils is calculated accounting for eddy currents in the copper solid turns. The solution is found first by an integral equation method applied to the stacks of solid plates of finite cross section and length. Then, the results are compared with the solution by the 3-D finite element code in the exact formulation. The proximity effect of the finite length of the conductor on the eddy current distribution is discussed. The example of the design of the coil with the targeted field orientation is presented. The unidirectional magnetization of isotropic permanent magnets is then discussed.
