Abstract
According to one embodiment, a method can comprise: providing a tool that has a first portion that comprises a first material and a second portion that comprises a second material, wherein the second material differs from the first material and the tool is subject to a magnetic field, and wherein the first material and the second material are provided such that the magnetic field is relatively stronger at and adjacent the first portion relative to the magnetic field at and adjacent the second portion; positioning a surface adjacent to the tool so as to be subject to the magnetic field; and disposing magnetizable abrasive particles on the surface, wherein the magnetizable abrasive particles are attracted to an area on the surface adjacent the first portion where the magnetic field is relatively stronger so as to provide for at least one of a desired orientation, placement and alignment of a majority of the magnetizable abrasive particles on the surface.
