Tesla's anti-gravitation engine (EM)

[heartless]

Hello,

Here on this movie:

at 19:35

There is shown Tesla's engine, which balances EM forces, that are able to raise a piece of metal into the air which then keeps on staying there.
If anybody is familiar with this, can you provide a name of this for me, architecture of this engine and if possible, some Tesla's notes on the construction of this? And else, if you don't possesses any known websites about the description, can you tell me how it actually works on a deeper level?

Thanks

It's just magnetic levitation, nothing to do with anti-gravity. Google for "magnetic levitation train" and "linear induction motor".
