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.79% similarUnverifiedType-II superconductors (such as niobium, superconducting alloys, and most high-temperature superconductors) form a mixed state in a magnetic field, allowing magnetic flux to partially penetrate the material in the form of quantized vortices.65% similarUnverifiedThe confinement pressure of fusion plasma is proportional to the fourth power of the magnetic field strength, meaning doubling the magnetic field strength results in a 16-fold increase in confinement capability.63% similarUnverifiedThe plasma in an FRC maintains confinement through the magnetic field generated by its own induced current, requiring no external toroidal coils, resulting in a more compact structure.63% similar
