Generatore Omopolare homopolar generator

In italiano and english
E' improbabile che troviate la descrizione del generatore omopolare di Faraday in qualsiasi libro di testo universitario sull'elettromagnetismo. L'argomento più vicino che troverete è il normale generatore omopolare. La differenza fondamentale è che nel generatore di Faraday il magnete che produce il campo magnetico si muove o ruota insieme al conduttore dove ci si aspetta venga generata la tensione. Il suo funzionamento fu descritto per primo da Faraday nel 1831.Un disco metallico è incollato al magnete ad anello e la combinazione è ruotata mentre la tensione è misurata tra due contatti scorrevoli: uno situato al centro mentre l'altro può scorrere dal centro fino al bordo del disco.
Nel video misuro la corrente su un magnete (ex altoparlante) a 2400 giri/minuto, la tensione e' di circa 25-30 mV, la corrente è limitata dalla resistenza di contatti dei puntali e del tester stesso

English:
It is unlikely that you find the description of the generator of Faraday omopolare in any text book on university electromagnetism. The argument more near that you will find is the normal generator omopolare. The fundamental difference is that in generator of Faraday the magnet that produces the magnetic field is moving or wheel together to the operator where we expect is generated the tension. Its operation was described for first in 1831.A hard metal is glued to magnet to ring, and the combination is rotated while the voltage is measured between two contacts sliding: one located in the centre while the other can scroll from the centre to the edge of the disk. In the video I current on a magnet (former Speaker) to 2400 RPM, tension, and is about 25-30 mV, the current is limited by the resistance of contacts of arrows and of the meter itself more information in Italian on http://digilander.libero.it/bubblegate/weird1.htm

Max current 0.8 A whith this setup .the electrical contacts must be made through a "brush" or slip ring, which results in large losses at the low voltages generated. Some of these losses can be reduced by using mercury or other easily liquified metal (gallium) as the "brush"
The magnet is a circular ring from a loudspeacker. N pole on one side P pone on the other. A Conductor disk is glued on one side.
whe all is rotating, a tension from the center to the circonference is estabilited, can source tremendous electric current (10 to 10000 amperes) but at low potential differences (typically 0.5 to 3 volts) more on more on http://en.wikipedia.org/wiki/Homopolar_generator and related links

Very interesting, have you tried to test the current, how much amperage, intensity out of this. Could you describe where are the magnets? I only see the rotating disk, it seem to be a rotating magnet?

what if you use plasma discharges into the air to move the magnet?
