1. A device for measuring and predicting spin and trajectory vectors of a moving ball, comprising:

  • at least one means for generating a magnetic field;

    a conductive, charged and/or magnetized modified ball;

    means for holding the at least one means for generating a magnetic field;

    at least one means for sensing electromotive force induced signals resulting from disturbances in the magnetic field by passage of the conductive, charged and/or magnetized modified ball through the generated magnetic field; and

    means for processing the electromotive force induced signals resulting from disturbances in the magnetic field to thereby predict the complete flight and final roll-out of the conductive, charged and/or magnetized modified ball.
