Abstract

The role of azimuthal forces as a factor hindering the manufacture of quasi-force-free magnet windings is shown. It is established that these forces are caused by the transverse magnetic field that arises due to deviations of a real winding from the calculated configuration. Model experiments confirmed the existence of a transverse field and showed the possible correction of the magnetic system. For this purpose, we propose to use additional unclosed conducting screens (compensators).
