Abstract
This paper considers three variants of MHD induction pumps: a centrifugal magnetovortex pump, a transformer type pump with magnetic asymmetry and a travelling field pump. All these pumps have a flat channel placed between the poles of one or several ferromagnetic cores inducing an alternating magnetic field directed normally to the channel plane. To describe electromagnetic forces generated in the pump channel, a mathematical model is proposed. The results of numerical and physical experiments are presented. Tables 1, Figs 13, Refs 7.
