Magnetic fields in electrochemistry: The Lorentz force. A mini-review

• Recent results in electrochemistry based on the Lorentz force.
• Focus on micro-magnetohydrodynamics.
• Magnetic field effects on chirality, hydrogen bubble release and nucleation.
• Suggestion for future work on molecular dynamics.

Some recent work on the flow induced by uniform or non-uniform magnetic fields acting on currents in an electrochemical cell is reviewed. The effects include modifying the structure and texture of electrodeposits including their chirality, controlling hydrogen bubble release, inducing microfluidic flow and influencing nucleation. Much of this depends on micro-magnetohydrodynamic flow, on a scale of microns.
