An effort was made to obtain a simplified mathematical model of wear particle motion in a magnetic field formed between flat and dimpled surfaces during the friction process. The magnetic field’s experimental values on the dimple edge and inside the dimple for several materials are presented. As a direct result of the internal magnetic field’s excitation at the edges of indentations, debris falls into the dimple. This reduces the wear rate by decreasing the number of abrasives in the friction interface. Apparent results expand ideas about the phenomena that naturally occur during the friction of textured surfaces.
