This document discusses electromagnetic pumps. It begins by introducing the concept of using electromagnetic forces to pump liquid metals based on Fleming's Left Hand Rule. It then describes three main types of EM pumps: conduction pumps, induction pumps, and thermoelectric pumps. The document notes that the two main applications of EM pumps are for cooling nuclear reactors and transporting molten metals in foundries. It provides diagrams and descriptions of the internal components and functioning of EM pumps, including how they use a transformer effect to induce high currents in the liquid metal. Finally, it outlines the advantages of EM pumps having no moving parts but limited uses due to power losses and requirement of electrically conductive liquids.
