<p>In an electromagnetic pump, an electrically conductive fluid is moved along a conduit (12; 28) by creation of a magnetic field across the conduit and a current flow perpendicular to the magnetic field, or by a series of pairs of opposed electromagnetic coils (32, 40) spaced along the conduit and energized so that each pole of each coil alternates in polarity and is always opposed across the conduit by a pole of opposite polarity, so that magnetic field lines across the conduit move along it.</p> |
