Electromagnetic pump

An electromagnetic pump is a pump that moves liquid metal, molten salt, brine, or other electrically conductive liquid using electromagnetism.

A magnetic field is set at right angles to the direction the liquid moves in, and a current is passed through it.

A magnetic field (brc) always exists around the current (I)-carrying conductor.

The two magnetic fields Bap and brc attempt to align with each other.

Designed for the Einstein–Szilard electromagnetic refrigerator (not the pumpless Einstein refrigerator), it uses electromagnetic induction to move conductive liquid metal without electrodes, to compress a working gas, pentane.
