2. Tokamak
   The leading magnetic confinement fusion concept named after a Russian word for toroidally (or doughnut) shaped magnetic field. The field the long way around the torus is the toroidal field and is the main confining field for the particles. The toroidal field is produced from a set of poloidally cons...

3. Tokamak
   doughnut-shaped closed configuration,where a strong electrical current circulates through the plasma,thus generating an extra magnetic field which grips the plasma securely so as to prevent it from spilling out of its magnetic container,and at the same time heating the plasma to the ignition temperature Category: Medicine

7. Tokamak
   A `tokamak` is a device using a magnetic field to confine a plasma in the shape of a torus (doughnut). Achieving a stable plasma equilibrium requires magnetic field lines that move around the torus in a helical shape. Such a helical field can be generated by adding a toroidal field (traveling around...
