A tokamak is a toroidal plasma confinement device invented in the 1950s by the Russians Tamm and Sakharov. The word "tokamak" is a contraction of the Russian words :"toroidalnaya", "kamera", and "magnitnaya", meaning "toroidal chamber-magnetic. "The plasma is confined here not by the material walls(which wouldn’t be compatible with a plasma which will be millions of degrees Celsius), but by magnetic fields. Physicists have been working since the 1950s on making better "magnetic bottles", a problem which has been compared to holding jello(the plasma) with rubber bands(the magnetic field). The magnetic fields in a tokamak are produced by a combination of currents flowing in external coils and currents flowing within the plasma itself. This contrasts to a similar concept, the stellarator, in which all of the confining magnetic fields are produced by external coils.  4, record 4, English, - JT%2D60
