Abstract
It is usually accepted that in linear induction pumps and chute systems the transversal end-effect manifests itself as a deformation of the current induced in the working medium that results in decreasing the electromagnetic force, affecting the working medium. This is true at small non-magnetic gaps. With large gaps, dissipation fields should be accounted for. This phenomenon is very conspicuous in devices with a single-sided inductor. The paper reports the theoretical and experimental results on the definition of electromagnetic forces, affecting electrically conducting bodies subjected to the field induced by a one-sided inductor with different non-magnetic gaps.
