By means of a system of two concentric coils, around which the current circulates in contrafase I have been able to make levitation freely to an aluminum disc. The calculation has been quite troublesome with many parameters to consider, some geometric ones: diameter of the disc, thickness, weight, inner and outer height of the windings, diameters of such. Other electrical ones: voltage of feeding, frequency, number of turns of the windings, diameter of the conductors of such. The effort was worth the trouble, is the disc there levitation freely, offering the possibility me of making turn it manually and verify the fabulous inertia of the system since the only present friction is with the air.
