Lorentz Force in MHD Conduction Pump Explained
Lorentz force explanation in a magnetohydrodynamic (MHD) liquid metal pump. The following setup is an MHD conduction pump which uses magnetic field of permanent magnet and DC current (up to 1000 A) to create perpendicular Lorentz force that drives the flow. Video detailly shows the cross product of current and magnetic field with vector field representation.
