THREE AND FOUR COIL SYSTEMS FOR HOMOGENEOUS MAGNETIC FIELDS

摘要

Very homogeneous fields are needed in the magnetic testing of spacecraft. One method of obtaining such fields is to use a number of circular coils on a common axis. The parameters of the best three and four coil systems were obtained by setting to zero as many terms as possible in the equation for the field along the axis of the system. The parameters are presented in the form of tables and curves.
