When the magnetic abrasive is attracted to a magnetic field, the abrasive particles will orient along the magnetic lines of force to form a magnetic brush [1,2]. When these magnetic brushes move relative to the workpiece surface, the micro-protruding edges on the workpiece surface can be removed by the grinding action of abrasive particles.
