DOE Explains...Tokamaks | Department of Energy
The total magnetic field (in black) around the torus confines the path of travel of the charged plasma particles. A tokamak is a machine that confines a plasma using magnetic fields in a donut shape that scientists call a torus. Fusion energy scientists believe that tokamaks are the leading plasma confinement concept for future fusion power plants.
