The research progress of the electro-deposition technology under the external magnetic field is introduced. During the electroplating process, the external magnetic field has an effect on solution properties, mass transfer, charge transfer, crystal growth and crystal orientation, etc. The magnetic field’s working principle during the material preparation is illustrated, and its specific impact during the electroplating is also classified and summarized. The problems in the field of the electroplating and the development prospects of the magnetic field application are also expatiated.
