The representative devices of magnetic confinement fusion are the tokamak (such as ITER) and the stellarator, whose advantages are long plasma confinement times and relatively clear physical mechanisms, while the disadvantages are enormous device size and extremely high construction costs.

UnverifiedTokamaks confine plasma using a toroidal magnetic field and the plasma's own current, have a relatively simple structure but tend toward pulsed operation and are prone to disruptions; stellarators rely on external coils to generate a three-dimensional helical magnetic field, are suitable for steady-state operation, but are more difficult and costly to manufacture.74% similarUnverifiedThe tokamak is currently the most mainstream form of magnetic confinement fusion device, using strong magnetic fields to confine plasma at hundreds of millions of degrees Celsius in a toroidal chamber to induce fusion reactions between deuterium and tritium.73% similar
