Magnetic confinement is a method used to contain hot plasma, which is essential for nuclear fusion. It employs powerful magnetic fields to keep the plasma stable and prevent it from touching the walls of a containment vessel. This technique is crucial for achieving the high temperatures and pressures needed for fusion reactions, similar to those occurring in the sun. One of the most well-known devices that utilize magnetic confinement is the tokamak. In a tokamak, the magnetic fields are generated by coils and help to create a toroidal, or donut-shaped, plasma. This design aims to maintain the necessary conditions for sustained fusion, potentially providing a clean and abundant energy source.
