ABSTRACT

It is shown that the varying of the configuration of the end faces of the Helmholtz coils from planar configuration to ellipsoidal configuration leads to an increase in magnetic field induction and in the uniformity level of the field in the working gap of the system. A modification is suggested of the thread-like currents technique for the calculation of magnetic fields. The analysis is carried out of the fields structure in various versions of the Helmholtz coils.
