I doubt it. The speed is fairly constant irrespective of orientation. The voltage from the coil on the meter is 5.92 volts, which seems to match the sluggish performance of the motor compared to its speed when running on the 9 volt battery. Note that the flat plate glued to the coil is a magnet. Missing is a 360ยบ panoramic view showing whether or not there is a large radio tower or high voltage overhead wires nearby. The main coil is centre tapped (approximately) by the perpendicular coil, which I think may be related to full wave rectification. The whole thing is reminiscent of the Avramenko Plug. One or more solder joints may function as a diode. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
