The first magnet (9) is set free to tumble within a tumbling chamber (10). A coil (11) wound around the out surface of the tumbling chamber (10). The two ends of the coil (11) are connected to the terminals of an LED (light emitting diode) (3). There may be some arbitrary, relative motion between the first magnet (9) and the second magnet (2). The magnets depicted with dotted lines represent alternative, relative motions of the second magnet (2) with respect to the first magnet (9). As the first magnet (9) and the second magnet (2) pass close to one another, the mutual interaction of the magnetic fields is sufficient to cause the first magnet (9) to tumble in the tumbling chamber (10). As the first magnet (9) tumbles in the tumbling chamber (10), a varying magnetic filed flux is effected through the coil (11) and a corresponding electric current flows through the coil (11) thus illuminating the LED 3.
A tumbling magnet electricity generating system for supplying electricity to at least one electrical device, comprising a tumbling chamber (10), a first magnet (9) arranged within the tumbling chamber (10), a second magnet (2) arranged externally to the tumbling chamber (10), and a coil (11) looped around the tumbling chamber (10), adapted such that the tumbling chamber (10) is of sufficient dimensions to allow the first magnet (9) to freely tumble, and such that on proximal relative motion of said first and second magnets, the mutual interaction of the magnetic fields is sufficient to cause the first magnet (9) to tumble in the tumbling chamber (10), generating a varying magnetic flux through the coil (11) such that a corresponding potential difference is formed across opposite ends of the coil (11), generating electricity to run an electric appliance.
