Magnetic Confinement

Method of containing a plasma or charged particles in a finite region using magnetic fields. Charged particles travel in helical paths around the magnetic field lines and this confines their motion to the local vicinity of the magnetic field. A properly shaped magnetic field prevents particles from escaping the confining field. One example of a magnetic confinement device is a tokamak.
