Abstract
An electromagnetic transducer includes a first member and a second member which are relatively slidable along a path having spaced endpoints and which are electromagnetically coupled. The second member has at least one winding which produces a magnetic field which penetrates the second member. The second member has a plurality of contiguous permanent magnets of alternate polarity along the path which establish a periodic magnetic field which reacts with the magnet field created by the first member so as to produce force along the path. The plurality of contiguous permanent magnets are disposed along the path such that transition lines dividing adjacent ones of the magnets are formed at a non-perpendicular angle to the path to allow gradual transition between flux directions.
