can anyone tell me how to levitate an object?

Answer 1

They are many ways. What do you want to levitate?

Magnets are the best method to levitate objects, but we need super-conductive magnets for large objects. Electric levitation works pretty well.

We are able to suspend atoms and molecules with light, magnetic fields, electric fields, and pressure waves (or acoustic).

Hopefully, some day we will find a more complete theory of gravity and find the particle that carries the force. So, that we use a anti-gravity force could offer a more efficient form of levatation.

Answer 2

Magnets are your best bet. It doesn't take a particularly powerful magnet to exceed the force of gravity. Normally, if you put a magnet on top of another magnet, such that like poles (which repel) are facing each other, there will be a small moment of force, causing the magnet to flip. Then the unlike poles are facing each other and they are attracted, so the magnets stick together. But if the magnets were placed within some sort of guide to prevent flipping, the magnetic repulsion would exceed the downwards force of gravity on the upper magnet, and it would remain suspended.

Magnetic levitation is such a common application that it has a nickname, maglev. Maglev has been widely explored for applications in transportation, because a maglev train doesn't have to deal with wear and tear on the wheels or tracks, allowing much higher speeds.

Answer 3

Basically, you need to apply a force to counter and balance gravity to keep an object levitated. Magnets will work, or air pressure.

Answer 4

Simply create a meta-material with a perfectly negative refraction index and insert it between two pieces of metal nanometer's apart... of course ;)

Answer 5

magnetize the object if it is a metal and keep it o top of a magnet of opposite polarity...it will float.

Answer 6

It is quite complex but is done today with maglev trains.

Answer 7

A magician can tell you.
