Abstract

In this paper we consider the numerical calculation of the values of the axial and plane components of the magnet-ic field of a three-dimensional ring with a current. The magnitude and direction of the magnetic induction vector is determined depending on the coordinates along the axis and in the plane of the ring. A formula for the planar com-ponent of the magnetic field of a three-dimensional ring with a current is obtained by numerical calculations. The results of experimental measurement of the magnetic field using a Hall sensor are presented and their good agree-ment with numerical calculations is shown.
