Rotationally activated generator

At least one focus magnet (typically a small disk magnet) having axially opposing magnetic poles, each being arrange across each side substantially along a line parallel to the rotational axis of the cylindrical magnet within the frame, to cause the cylindrical magnet's field to be pulled into a more concentrated alignment so that more moving magnetic field lines from the cylindrical magnet can cut through the coil windings when the cylindrical magnet is rotated by an externally applied force.
