Plasma confinement device

A device and method for magnetic field confinement of plasma is formed by a cylindrically stacked column of direct current-carrying magnetic field coils with electrodes adjacently interior to each magnetic field coils so as to induce plasma rotation about an annular confinement region. Each field coil produces a magnetic field alternating in direction relative to adjacent coils and, so as to maintain consistent overall azimuthal direction of plasma rotation, electric field electrodes alternate accordingly in polarity along the axial length of the device.
