| titleOfInvention | Electromagnetic drive method and apparatus for driving a rotationally stabilized magnetically levitated object |
| abstract | An electromagnetic drive apparatus and method are operative to rotate a magnetically levitated object for an indefinite period of time. The object, such as a spinning magnetic top with a spindle, is levitated over a base magnet and a horizontal component of a pulsed magnetic field is applied at the region of the spinning magnetic top to maintain the top spinning and levitating indefinitely. The pulsed magnetic field is generated by applying a pulsed dc voltage or an ac current to a coil situated in proximity to the top. The coil may have a cylindrical or oblong shape and a core may be provided in the coil. Levitation stability and duration are improved by positioning a loosely fitting washer on the spindle of the spinning magnet so as to permit relative rotation therebetween during application of the pulsed magnetic field. |
