Charged particles can be confined in a spatial volume by means of the Lorentz Force. In order to minimize the interaction between the confined particles and the surrounding material structures, the required magnetic fields typically have a toroidal topology (see MHD equilibrium). In order to achieve fusion, the parameters of the confined plasma must satisfy the Lawson criterion.
