providing a 360 degree rotation path comprising the interior of the toroidal magnetic cylinder and an open magnetic area outside of the interior of the toroidal magnetic cylinder,
rotationally moving a coil segment along the 360 degree rotation path and producing a voltage in the coil segment as the coil segment rotationally moves through the first area of magnetic concentration,
removing the voltage from the coil segment,
rotationally moving the coil segment along the 360 degree rotation path into the open magnetic area,
positioning a first plurality of magnets along an interior wall of the partial toroidal magnetic cylinder where each of the plurality of magnets in the first plurality of magnets has a first common pole facing towards the interior of the partial toroidal magnetic cylinder,
positioning a second plurality of magnets along a first side wall of the partial toroidal magnetic cylinder where each of the plurality of magnets in the second plurality of magnets has a second common pole facing towards the interior of the partial toroidal magnetic cylinder,
positioning a third plurality of magnets along a second side wall of the partial toroidal magnetic cylinder where each of the plurality of magnets in the third plurality of magnets has a third common pole facing towards the interior of the partial toroidal magnetic cylinder, and
wherein first common pole, the second common pole, and the third common pole have the same magnetic polarity.

2. The method of claim 1 further comprising:
rotationally moving a second coil segment along the 360 degree rotation path and producing a voltage in the second coil segment as the second coil segment rotationally moves through the first area of magnetic concentration,
removing the voltage from the second coil segment,
rotationally moving the second coil segment along the 360 degree rotation path into the open magnetic area.

3. The method of claim 2 further comprising:
rotationally moving an additional coil segment along the 360 degree rotation path and producing a voltage in the second coil segment as the second coil segment rotationally moves through the first area of magnetic concentration,
removing the voltage from the additional coil segment,
rotationally moving the additional coil segment along the 360 degree rotation path into the open magnetic area.

4. The method of claim 1 , wherein the concentrating further comprises:
positioning a fourth plurality of magnets along an exterior wall of the partial toroidal magnetic cylinder where each of the plurality of magnets in the fourth plurality of magnets has a fourth common pole facing towards the interior of the partial toroidal magnetic cylinder, and
wherein first common pole, the second common pole, the third common pole, and the fourth common pole have the same magnetic polarity.

5. The method of claim 4 , wherein the concentrating further comprises creating a flux line from at least one magnet of the first, second, third, or forth plurality of magnets such that the flux line flows from the north pole of the magnet in a perpendicular manner from an interior face of the magnet, through the interior cavity of the toroidal magnetic cylinder, out an open end of the toroidal magnetic cylinder, into the open area, and then around an exterior of the toroidal cylinder to the exterior face of the magnet containing its south pole.

6. The method of claim 5 , wherein the formed flux line is dominantly aligned with the direction of the applied force acting upon the coil segment thereby reducing losses.

7. The method of claim 1 , wherein the providing a 360 degree rotation path further comprises adding a magnetic field of a differing magnetic polarity in the open magnetic area.

8. The method of claim 1 , wherein the providing a 360 degree rotation path further comprises providing a circular core upon which one or more coil segments may be positioned around.

9. The method of claim 8 , wherein the concentrating further comprises creating a flux line from at least one magnet of the first plurality of magnets, the second plurality of magnets, the third plurality of magnets or a fourth plurality of magnets such that the flux line flows from the north pole of the magnet in a perpendicular manner from an interior face of the magnet, through the interior cavity of the toroidal magnetic cylinder, through the circular core, out an open end of the toroidal magnetic cylinder, into the open area, and then around an exterior of the toroidal cylinder to the exterior face of the magnet containing its south pole.

10. A method of producing a radial motion of a shaft, the method comprising:
concentrating similarly polarized magnetic flux forces within an interior of a partial toroidal magnetic cylinder to create a first area of magnetic concentration comprising a plurality of similarly polarized magnetic flux forces,
