1. A device comprising:

  • a plurality of electric coils arranged in the shape of a toroid and configured so that, upon the application of electric current through the plurality of coils, adjacent coils generate magnetic fields of opposing polarities;

    a primary rotor mounted within the plurality of electric coils for rotation relative to the plurality of electric coils, the primary rotor including a plurality of permanent primary magnets configured as a Halbach cylinder having a magnetic field substantially confined within the cylinder;

    a secondary rotor mounted coaxially with the primary rotor externally of the plurality of coils and for rotation relative to the plurality of electric coils, the secondary rotor including a plurality of permanent secondary magnets configured as a Halbach cylinder having a magnetic field substantially outside the cylinder and configured to magnetically couple with the Halbach cylinder of the primary rotor; and

    means for conducting electric current between the plurality of electric coils and an electric apparatus.
