Abstract

The work considers two circular loops of different radii with a common center and plane. The magnetic field has been determined in a plane parallel to the loops plane and passing through the axis of the system symmetry. It is assumed that the field in the loops center reaches zero, and the distance to the observance plane is equal to the size of loops, it means that the field is estimated in the proximal area.

The method for estimating magnetic fields produced by two circular currents in their opposite directions has been presented. For determining the magnetic field induction produced by a flat closed loop at the random point the classical formula of the Biot-Savart-Laplace law is used. The basic formulae and results of numerical calculation of distribution of magnetic fields generated by such system are given. It is shown that the local maximum of magnetic induction vector arises along the axis of symmetry. These results can be used for magnetic carriers confinement during magnetic therapy
