Tokamaks 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.

UnverifiedThe 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.79% similarUnverifiedThe 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.74% similarUnverifiedMagnetic reconnection is a fundamental process in plasma physics: when magnetic field lines of opposite direction approach each other, they reconnect and change their topological structure, rapidly converting magnetic energy into plasma kinetic energy and thermal energy, and it is considered the energy release mechanism for phenomena such as solar flares, Earth's magnetospheric substorms, and sawtooth oscillations in tokamak devices.74% similarUnverifiedHall-effect thrusters use a magnetic field to trap electrons and form an electron cloud, with the magnetic field acting as a virtual grid, avoiding grid erosion, and their operational lifespan is generally better than that of traditional gridded designs.73% similar
