Calculation of electromagnetic fields and forces in coil systems of arbitrary geometry
Abstract
A computer program is described which calculates the electric and magnetic fields due to an arbitrary spatial distribution of current carrying circular loops, circular arcs, and straight lines. The electric field is assumed to arise solely from the time variation of the magnetic field, and the magnetic field due to the changing electric field is assumed to be negligible. In addition, the conductor bundle elements (loops, arcs, lines) are assumed to be absent. Electric and magnetic flux lines and magnetic forces and inductances are also calculated. The algorithm used in the code, which is based on a combination of direct and numerical integration using the Biot Savart law, is discussed. The methods used to maintain accuracy in calculating fields within the conductor bundle, in particular, are detailed. Several examples are then presented to illustrate the input and output features as well as the accuracy obtained and the running time required.
