In [[tokamak]]s, a significant part of the confining magnetic field is produces by the currents flowing in the plasma itself.
In contrast, the confining magnetic field of [[stellarator]]s may be dominated by externally imposed magnetic fields (depending on the configuration).
Since the confinement properties of toroidally confined devices depend sensitively on the magnetic field, the question arises whether this external control may be used to improve confinement properties, and thus facilitate the development of an economically attractive [[stellarator reactor]].

Several optimization strategies have been developed and/or are being studied.
