It has been reported by one of the authors that the vertical magnetic field of 0.01 and 0.13 Tesla increases the width of wear scar suffered from fretting under Hertzian contact conditions between a steel ball and a disk. In this report, the effects of the direction (i.e., vertical and horizontal) and the density (from 0.3 to 0.5 Tesla) of magnetic field on fretting wear are examined under applied load from 75 to 158N. The tests have been carried out using bearing steel disks and balls. The width of wear scar annulus increased with increasing the density for both of the vertical and horizontal magnetic fields. A difference in appearance of wear scars fretted in vertical and horizontal fields can be seen. A possible mechanism of fretting wear under magnetic field has been proposed.
