Abstract
A method for positioning permanent magnetic blocks includes providing a plurality of magnetized blocks, positioning the magnetized blocks on a yoke in a row by applying a mechanical force at a first end of the row with a first clamping member and at a second end of the row with a second clamping member, and repositioning the blocks by reducing the mechanical force at the first end by moving the first clamping member away from the first end, and moving the second clamping member toward the second end.
