Application of permanent magnets for forming solenoidal fields

Abstract

In the paper the possibility of forming a solenoidal magnetic field with the help of the permanent ring-shaped magnets is considered. The results of modeling a magnetic field for the magnets with the various inside diameter is shown. The possibility of the magnitude control of the magnetic field by the passive and active methods is investigated. In the work the estimation of the cost, mass and size of various magnets was done.
