A limited amount of material will be removed by conducting a relative motion between the work surface and the abrasives, so as to obtain a mirrorlike finished surface. Owing to the magnetic field, the magnetic abrasives will gather to form a flexible magnetic brush. Thus the magnetic abrasives can move and polish along the profile of a complex surface, so the surface with
