A mechanism for varying the position of a band saw blade in a tilting frame band saw. The methods for producing a corn plant by crossing the inbred line G2202 are also encompassed by the invention. Points of application of the Lorentz forces on first and second coils of the two coils are in different positions with respect to each other, viewed in a direction parallel to the first direction. Second, the CCL leads to a narrow current flow profile at the side region, therefore producing a narrow track width definition.
