Quick Summary

An electromagnetic pump, also known as an MHD (magnetohydrodynamic) pump, is a device that uses electromagnetic force to move fluids. This type of pump can only be used with fluids that are good electrical conductors, such as liquid metals.1

The principle behind an electromagnetic pump is similar to that of an electric motor. The pipe carrying the conductive fluid is placed within a magnetic field, and an electric current is passed through the fluid perpendicular to the magnetic field. This interaction generates an electromagnetic force that propels the fluid in the direction of flow. These pumps are utilized for circulating liquid metals, which are often used as coolants in nuclear reactors.1
