A magnetic levitation system is described, including a first cylinder-shaped magnet; a second cylinder-shaped magnet coaxially aligned with the first cylinder-shaped magnet; and a first cavity coaxially aligned with the first cylinder-shaped magnet; wherein the surfaces of the like-poles of the first and second cylinder-shaped magnets are parallel to each other and face each other to result in a linear magnetic field between the first and the second magnets. Methods of using a magnetic levitation system for analyzing a diamagnetic or paramagnetic sample are also described.

A magnetic floating speaker includes a seat having a shell and a magnetic floating controller and a lower magnet both received in the shell. A floating member floating and located above the seat has a cover, a bass unit, two full range units and an upper magnet all received in the cover. The magnetism of the upper magnet and the lower magnet is mutually exclusive. The bass unit is surrounded by said two full range units and faces to a first direction, said two full range units face to a second direction and a third direction respectively which located at two sides of the first direction, the second direction and the third direction each forms an acute angle with the first direction respectively.

A reluctance transducer includes a soft ferromagnetic yoke and a soft ferromagnetic core element, which is movable relative to the yoke. Two permanent magnets bear the core element. The permanent magnets are arranged relative to each other and to the yoke so that the reluctance transducer has a good linear relationship between displacement and force. The reluctance transducer can be applied as stiffness compensating element. The reluctance transducer can include an electrical winding to allow its application as a magnetic bearing, an actuator or as a displacement, velocity or acceleration sensor with improved intrinsic linearity.
