Three-dimensional calculation of the magnetic field created by current-carrying massive disks

This paper deals with a complete three-dimensional calculation of the magnetic vector potential and of the magnetic flux density created by disk conductors, in which an assigned current flows. The formulas presented are valid either inside or outside the conductor. The effectiveness and the time-saving possibilities of the expressions derived is shown by comparison with the numerical results obtained by direct integration of the Biot-Savart formulas and with experimental results.
