Abstract
A small, direct current electromagnetic conduction pump was
designed according to the equivalent circuit theory of A. H. Barnes.
Design was aided by data from a prototype also constructed by the
authors. Distinguishing features of the pump are its small size, the
use of non-conducting pump walls, and the use of mercury as the working
fluid. Performance was compared with theory. Deviations were attributed
to electrode contact resistance and to the interaction between magnetic
leakage flux and fringe current. Contact resistance to mercury of
rhodium and nickel electrodes was determined with the aid of a jig
designed for the purpose. A magnet design using flux plotting techniques
is presented. Distinguishing feature of the magnet is its cylindrically
shaped yoke.
