1000 Amps with 1 Volt – MHD pump

1000 Ampere magnetohydrodynamic (MHD) liquid metal pump demonstrates Lorentz force in laboratory model. The following setup is an MHD conduction pump which uses magnetic field of permanent magnet and DC current to create perpendicular Lorentz force that drives the flow.
