1. A magnetic field production system, comprising:

  • a device selected from the group consisting of a machine and a system;

    a two-dimensional winding configuration having two windings disposed substantially orthogonally with respect to one another and enclosing said device, said two windings having winding axes disposed substantially at right angles to one another; and

    two feed circuits connected to said two windings and supplying alternating variables to said two windings, said two feed circuits include a first feed circuit outputting a first alternating variable and a second feed circuit outputting a second alternating variable, the first alternating variable and the second alternating variable having equivalent frequencies, similar current amplitudes, similar voltage amplitudes, and being synchronized to one another, the first alternating variable having a phase shift with respect to the second alternating variable.
