  • Publication number: 20240071670
    Abstract: Apparatus, systems, and methods of construction and use to produce linear, rotational or counter-rotational motion, acceleration, and actuation by the use of moveable ferromagnetic, electromagnetic, conductive, or permanent magnetic objects. The moveable objects are oriented to produce or to be acted upon by asymmetric electromagnetic field distributions, thereby resulting in motion of the magnetic objects. Further, exemplary embodiments and applications are described herein.
