A helical coil of wire energized electrically to produce a magnetic field, which induces a current in any conductor placed within or near the coil.

solenoid

(sōl′lĕ-noyd)
A coil of insulated wire in which a magnetic force is created in the long axis of the coil when an electric current flows through the wire. It may be used to activate switches.

Wurden said that the FRC configuration had fusion reactor promise because it has "low complexity due to low magnetic field and a solenoidal magnet system with a natural linear divertor.
This condition requires that the vector cDv, having physical dimensions of energy per unit surface, is solenoidal i.
Biasing of an inner core relative to the outer wall produces a radial electric field which will drive supersonic azimuthal rotation and the resulting centrifugal force will contain plasma to the solenoidal portion.
Solar cells and solenoidal magnet coils would create a dense, magnetized plasma that would generate an electromagnetic field 10 miles to 12 miles in radius around the spacecraft.
