1. A magnetic field emission structure, comprising:

  • an array of magnetic field emission sources each having positions and polarities relating to a spatial force function; and

    at least one current source associated with at least one of said array of magnetic field emission sources, said at least one current source generating an electric current to change said spatial force function, said spatial force function corresponding to a code modulo defined by a code, said code modulo having a peak spatial force and a plurality of off peak spatial forces, said plurality of off peak spatial forces having a largest off peak spatial force, said largest off peak spatial force being less than half of the peak spatial force.
