How Tokamaks Work to Make Nuclear Fusion Possible
A tokamak is a machine that uses strong magnetic fields to hold superhot plasma in place. This confinement is what could make nuclear fusion possible. Research has advanced, but big engineering challenges remain, and no tokamak has yet produced net energy for commercial power.

Context: Fusion joins light atoms to release energy, the same process that powers the sun, and it is often pitched as a clean future power source. Tokamaks, a doughnut-shaped design, are the most widely studied approach to fusion worldwide.
