Using guanine micro-crystals with light-reflective surfaces as a fluid tracer, magnetohydrodynamic (MHD) flows were visualized in silver electrodeposition under a magnetic field of 2 T. The trace of a guanine particle showed macroscopic MHD laminar flows at a low deposition current of 50 μA. On the contrary, at a high current of 200 μA, the trace exhibited a zigzag walk and vortex motion with the sizes of 100 ∼ 500 μm. This behavior demonstrates the existence of micro-MHD vortices that play a crucial role in chiral surface formation.
