Anti-gravity suspension device refers to a device that objects can be suspended without contact force such as pressure. At present, there are two kinds of anti-gravity suspension devices: magnetic suspension device and pneumatic suspension device. Similar to the anti-gravity device in science fiction movies, it does not exist in reality. The method of self-made suspension anti-gravity equipment is as follows:

Magnetic levitation uses the principle that magnetic fields repel each other. The simplest magnetic levitation device is to put two magnets with the same magnetic poles together, and the repulsion of the magnets will make the magnets above float against their own gravity, which constitutes the simplest gravity levitation device.

At this time, it will be found that the suspended magnet is easy to fall off, and a binding device is needed to prevent the suspended magnet from falling off. This binding device can be a bottle, a box or a wooden stick. If you have a good center of gravity, you don't need to add a binding device. )

Extended data:

There are three kinds of magnetic levitation in the world:

1, normally conductive magnetic levitation represented by Germany,

2. Superconducting magnetic levitation, normal magnetic levitation and superconducting magnetic levitation represented by Japan all need electricity to generate magnetic levitation power.

3. It is China's permanent magnet suspension, which adopts special permanent magnet materials and does not need any other power support.
