A stellarator is a magnetic confinement device. The rotational transform is predominantly generated by external coils - as opposed to a tokamak, in which the poloidal field is generated by plasma currents. Hybrid concepts employ both external coils and self-generated (bootstrap) currents (e.g. NCSX).
