Abstract

A magnetically levitated ball comprises a sphere, a segment, a base and the like, the sphere is hollow, the segment with a strongly magnetic block is arranged in the sphere, a top disk with balls is connected with the upper surface of the segment through an upright, the base is made into the shape of a table, the upper plane of the base is provided with a wok-shaped magnetic pit, and the magnetic polarities of the opposite surfaces of the magnetic pit and the magnetic block in the segment are the same. When the sphere is put into the pit, the magnetic block in the segment is pushed upward by the repulsion of the magnetic force, and drives the sphere to go up by means of the upright and the top disk on the segment, the sphere is levitated in the air over the table when the magnetic force is equal to the earth gravity, and moreover, the sphere can be rotated in any direction in order to achieve better visual and demonstration effects.

Description

Magnetic levitation ball

Technical field

The present invention relates to a kind of magnetic levitation system, specifically a kind of magnetic levitation spheroid.

Background technology

Conventional magnetic levitation ball or magnetic levitation terrestrial globe generally can not be done the rotation of multidirectional angle, therefore have a strong impact on vision and demonstration effect.

Summary of the invention

Can make the problem of multidirectional angle rotation in order to overcome magnetic levitation ball, the invention provides a kind of magnetic levitation ball, this magnetic levitation ball not only can be done the rotation of multidirectional angle, and comprises a plurality of mechanics principles, without external power supply.

The present invention solves the technical measures that its technical matters takes, make the spheroid of hollow shape with plastics or nonmagnetic metal material, the inner wall smooth of spheroid, hollow segment of internal fixation at spheroid, segment places the bottom of sphere cavity, its maximum gauge is slightly smaller than the diameter of sphere cavity co-located, the ferromagnetism piece is installed in the hollow cavity of segment, its effect one is that a magnetic field is set in spheroid, the 2nd, the weight of increase segment makes it that downward center of gravity be arranged all the time, the sphere smooth in appearance of segment, planar central is fixed a column that makes progress on segment, the top of column connects the circular dish of going up, and around the last dish ball is set, when segment upwards leaves sphere inner wall lower end one segment distance, ball around the last dish contacts with spheroid upper end inwall, and can slide along sphere inner wall; Make the base of billiard table shape with nonmagnetic substance, scrape out the pit of pot shape under the last plane of base, the just in time seat of spheroid is gone in the pit, surface layer at pit is provided with magnetic block, this magnetic block is identical with the forward surface polarity of property piece in the segment, can produce mutual repulsive force, when spheroid is put into pit, magnetic thrust upwards pushes away segment, the dish of going up of segment withstands sphere inner wall simultaneously, drives whole spheroid upwards, when magnetic force equates with the ground mental and physical efforts, spheroid just can be suspended in the aerial of billiard table top, if at this moment remove to stir spheroid, the segment center of gravity under action of gravity in the spheroid is downward all the time, under the magneticaction of pot shape distribution magnetic block, the center of gravity of segment is aimed at the center of pit always, can be not to the left and right, the front and back drift, therefore the ball that coils on the segment when stirring spheroid gently contacts slip with sphere inner wall, and spheroid can be done the rotation of any angle under suspended state, multidirectional angle rotation be can do thereby reach magnetic levitation ball, vision and the purpose of demonstrating effect improved.

The invention has the beneficial effects as follows, show the ultimate principle of magnetic levitation technology and mechanics, explore wherein secret and generation reverie, simple in structure.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing.

Accompanying drawing is the structural representation of magnetic levitation ball.

Among the figure, 1, spheroid, 2, segment, 3, magnetic block, 4, inner chamber, 5, column, 6, go up dish, 7, ball, 8, base, 9, pit, 10, magnetic block.

Embodiment

In the accompanying drawings, spheroid 1 usefulness plastics or nonmagnetic substance system are hollow, segment 2 is set in sphere cavity 4, segment is made hollow, magnetic block 3 is installed, magnetic block 3 is made the segment shape, a root post 5 is fixed on the plane on segment, in the connection of the top of column, coil 6, around the last dish ball 7 is installed, when segment left inner chamber lower end one segment distance, the ball around the last dish contacted with inner chamber upper end wall body, column and last dish are made with light material, to alleviate top weight, base 8 usefulness nonmagnetic materials are made the billiard table shape, scrape out a pot shape pit 9 under plane on the billiard table, at the surface layer of pit the magnetic block 10 of magnetic is set, the polarity of this magnetic block is identical to the polarity of practising physiognomy with the magnetic block of segment.
