Embodiment Construction
[0009] In the figure, a hollow sphere 1 is made of a non-magnetic and light material, and a spherical-shaped magnetic steel 3 is arranged in the inner cavity 2 of the sphere. Column 4, ball 5 is set at the top of the column, when the magnetic steel floats up, the ball contacts the inner wall of the sphere, the base 6 is made into a cup shape, a pot-shaped magnetic block 7 is set at the bottom of the cup shape, and an annular magnetic strip 8 is set at the mouth of the cup. The magnetic blocks and magnetic strips have the same polarity as the facing faces of the magnetic steel inside the sphere. Usually the posts and balls are made of non-magnetic and lightweight materials.

The invention relates to a magnetically levitated globe. A sphere is hollow, a segment-shaped steel magnet is arranged in the sphere, three uprights with the top ends being provided with balls are fixed on the steel magnet, a base is shaped like a cup, a wok-shaped magnetic block is arranged on the bottom of the cup, an annular magnetic strip is arranged on the mouth of the cup, and the polarities of the opposite surfaces of the magnetic block, the magnetic strip and the steel magnet in the sphere are the same. When the sphere is placed into the mouth of the cup, the steel magnet is repelled by the magnetic force to levitate, meanwhile, the sphere is driven by the uprights to go up, thereby the magnetically levitated state is realized, and moreover, the globe can be rotated at any angle.
Description
technical field [0001] The invention relates to a magnetic levitation instrument, in particular to a magnetic levitation globe. Background technique [0002] Nowadays, most of the maglev globes sold on the market use a bow-shaped bracket to fix the magnetic block, which cannot rotate in multiple directions, thus affecting the visual and presentation effects. Contents of the invention [0003] In order to overcome the problem that the globe can make multi-directional angles, the invention provides a magnetic levitation globe, which overcomes the deficiencies of the prior art and improves visual and demonstration effects. [0004] The technical measure adopted by the present invention to solve the technical problem is to make a hollow sphere with a non-magnetic material, the inner wall of the sphere is smooth, and a magnetic steel in the shape of a spherical segment is arranged in the sphere, and the magnetic steel is located at the lower end of the inner cavity of the spher...
