Abstract
A device for flowing a fluid having electrical conductivity comprises a plurality of fluid passages annularly arranged such that electric current can flow across the adjacent passages and a magnetic field generating means for generating a magnetic flux crossing the plurality of passages in radial direction. The electric current induced by making the electrically conductive fluid flow in part of the fluid passages is caused to flow in loop through all the fluid passages. The electrically conductive fluid existing in the remaining fluid passages is caused to flow by the induced current and the magnetic flux produced in the magnetic field generating means, in synchronism with the flow of the fluid flowing through said part of the fluid passages.
