Abstract
The anodic dissolution of copper in NaCl solutions with the application of an external magnetic field of 450mT is studied by digital holography. The effects of the field on the basic electrochemical processes are visualized through reconstructed phase maps, which enable direct observation of the magnetohydrodynamic flow during the electrochemical mass transport. The magnetic field affects the anodic dissolution of copper in chloride media in two ways: restraining the formation of the CuCl salt layer, increasing the mass transport rate. The presentation of dynamic phase maps through the video enhances the power of digital holography in investigating electrochemical processes.
