1. A plasma confinement device, comprising:
a first magnet system comprising a first plurality of concentrically arranged circular-loop coils, comprising:
a first coil arranged to carry a current in a first direction; and
a second coil arranged to carry a current in a second direction opposite to said first direction; and
a second magnet system comprising a second plurality of concentrically arranged circular-loop coils, arranged with mirror symmetry with respect to said first magnet system relative to a symmetry plane located between said first magnet system and said second magnet system,
creating an annular plasma confinement area at said symmetry plane with a magnetic field normal to said symmetry plane at said symmetry plane.
