| Abstract: | The formula for computing the 3-dimensional axially symmetrical steady magnetic field for vectorpotential is derived by the spherical function expansion. Using this formula, the magnetic field both outsideand inside the region with current distribution can be calculated. The examples in which the formula has beenapplied are presented. |
