A magnetic field affects the moving path of electrolytic ions, from a linear path

to a curved (cycloid) path, and also accelerates the ions. This results in the improvement

of finishing efficiency.

(2) Surface roughness and metal removal improve at the same

time compared with the traditional electrolytic process.

(3) For the highest finishing efficiency, an optimal magnetic flux density exists and it

was 0.06 T for an electrode gap of 1 mm.

(4) For a specific magnetic flux density, the electrode gap determines the effectiveness

of the magnetic field on finishing efficiency. For an increase in finishing efficiency,

the gap was below 2 mm when the magnetic flux density was 0.06 T.

(5) The relationship between the magnetic flux density, the electrode gap and the

electrode potential determines the optimal condition at a specific value correlated for

the maximum efficiency of surface finish.
