A magnetron sputtering source for forming a sputtered film on a substrate in a magnetron sputtering apparatus includes a target having a surface from which material is sputtered and a magnet assembly that is rotatable about an axis of rotation with respect to the target. The magnet assembly produces on the target an erosion profile that is calculated to yield a desired depositional thickness distribution and inventory. A method for configuring the rotatable magnet assembly includes the steps of determining an optimal erosion profile that yields the desired depositional thickness distribution and inventory, determining a plasma track on the surface of the target that produces an acceptable approximation to the optimal erosion profile, and determining a magnet structure that produces the plasma track.
