Passive levitation in alternating magnetic fields

DWPI Title: Object levitating method of mass spectrometry, involves varying coupling between rotational and translational magnetic forces and maintaining one of forces steady in time by controlling alternating axisymmetric magnetic field
Abstract: Stable levitation of an object in an alternating magnetic field can be achieved by eliminating coupling between the rotational and translational forces acting on the object. Stable levitation can also be achieved by varying the coupling between the rotational and translational forces acting on the object, while maintaining one or more of the rotational and translational forces steady in time.
Use: Object levitating method of mass spectrometry.
Advantage: The stable levitation of object can be achieved by varying the coupling between the rotational and translational forces acting on the object, while maintaining one or more maintains one or more rotational and translational magnetic forces steady in time.
Novelty: The rotational and translational forces are applied on an object by positioning in an alternating axisymmetric magnetic field. The alternating magnetic field is controlled to maintain one of the rotational and translational magnetic forces steady in time, produce coupling between rotational and translational magnetic forces and to vary coupling between rotational and translational magnetic forces in a predetermined pattern.
