Here are the four phases of the Bedini circuit which follows the magnet on the rotor around clockwise from the top right picture:
Position 1 the approaching magnet induces a little charge in the trigger coil that doesn't do anything.
Position 2 magnet is top dead center over the coils and everything is dead.
Position 3 is where the trigger coil opens up the transistor switch so the Primary power battery can load up the primary coil electromagnetic field.
Position 4 is where the trigger coil shuts off the transistor switch causing the primary coil magnetic field to collapse which fires the 300 volt spike into the battery being charged. Inside the battery it creates a temporary dipole that captures the surrounding virtual photons and converts them into real photons.
