Abstract The effect of magnetic field velocity on the electrolytic process and the quality of Cu electrode used in
the sensor was analyzed.The results show that a more complex copper electrolysis reaction is formed by applying a
magnetic field.After increasing the magnetic field velocity, the mass loss of copper anode decreased, and the maximum
cathode precipitation appeared at the flow rate of 0.25 m/s.The magnetic field velocity has a significant effect
on the impurity ions in Cu electrode electrolysis stage.The concentration of impurity ions decreases after the magnetic
field is applied, and the actual effect is influenced by the magnetic field orientation and the flow velocity.At
the magnetic field velocity of 0.25 m/s, the maximum cathode precipitation rate can be obtained, thus reducing the
concentration of impurity ions in the electrolyte and reducing the copper loss.In the vertical magnetic field, the electrolyte
viscosity in the range of 0~0.75 m/s is basically constant, and reaches the minimum value at 0.25 m/s.Vertical
magnetic field can inhibit electron transport and enhance diffusion.With the increase of flow rate, Cu2+ diffusion
process was hindered, and the maximum cathode precipitation was obtained at the rate of 0.25 m/s.
