Tokamak Plasma Confinement

A Tokamak is a device designed to confine hot plasma, the fourth state of matter needed for nuclear fusion, where hydrogen nuclei fuse to create energy, similar to processes in the sun. It uses powerful magnetic fields to create a toroidal (doughnut-shaped) chamber, keeping the high-temperature plasma away from the reactor walls. This confinement is crucial, as the plasma must stay at extreme temperatures (millions of degrees) for fusion to occur. By maintaining stability and containment, Tokamaks aim to harness fusion energy, which promises a clean and nearly limitless energy source.
