Pulse-Charging Battery circuits

With this system, the rotor is started spinning by hand. As a magnet passes the triple-wound tri-filar coil, it induces a voltage in all three coil windings. The magnet on the rotor is effectively contributing energy to the circuit as it passes the coil. One winding feeds a current to the base of the transistor via the resistor R. This switches the transistor hard on, driving a strong current pulse from the battery through the second coil winding, creating a North pole at the top of the coil, boosting the rotor on its way. As only a changing magnetic field generate a voltage in a coil winding, the steady transistor current through coil two is unable to sustain the transistor base current through coil one and the transistor switches off again.
