ABSTRACT:
An electromagnetic pump and generator apparatus for electrically conductive fluids includes a conduit for containing the conductive fluid and apertures in the sides of the conduit. A fluid circuit is defined outside the conduit for containing a quantity of the conducting fluid and is configured so that the conducting fluid in the circuit is in fluid communication with the conducting fluid in the conduit. When used as a pump, a magnet produces a magnetic field across the conduit between the apertures and a device is employed to produce an electric current in the conducting fluid in the fluid circuit. Current in the conducting fluid in the fluid circuit flow across the conduit through the conducting fluid contained therein between the apertures. The current flowing across the conduit together with the magnetic field imparts a force on the conducting fluid in the conduit causing the fluid to be pumped. Conducting fluid in the fluid circuit is essentially static and functions primarily as a means for conducting current to and from the fluid in the conduit eliminating the need for solid electrodes.
