This is a simple magnetic levitator, which suspends objects a set distance below an electromagnet. The physics behind it is to simply provide a magnetic force which equal and opposite to the gravitational force on the object. Two forces cancel and the object remains suspended. Practically this is done by a circuit, which reduces electromagnet force when an object gets to close, and increases it when the object is out of range.
