Wikipedia
A '''tokamak ''' is a device that uses a powerful magnetic field to confine plasma in the shape of a torus. 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 the torus in circles) and a poloidal field (traveling in circles orthogonal to the toroidal field). In a tokamak, the toroidal field is produced by electromagnets that surround the torus, and the poloidal field is the result of a toroidal electric current that flows inside the plasma. This current is induced inside the plasma with a second set of electromagnets.
The tokamak is one of several types of magnetic confinement devices, and is one of the most-researched candidates for producing controlled thermonuclear fusion power. Magnetic fields are used for confinement since no solid material could withstand the extremely high temperature of the plasma. An alternative to the tokamak is the stellarator.
Tokamaks were invented in the 1950s by Soviet physicists Igor Tamm and Andrei Sakharov, inspired by an original idea of Oleg Lavrentiev.
The Tokamak Game Physics SDK is an open-source physics engine.
At its beginnings, Tokamak was free for non commercial uses only. Since May 2007, it has become open sourced under a BSD License. Now it can be used under BSD or Zlib license, in order to make the source code exchange with other physics engine possible.
Tokamak can refer to:
In Physics:
- Tokamak, a fusion reactor device
In Video Games:
- Tokamak physics engine, a Game Physics engine
In Comics:
- Tokamak, a fictional supervillain for DC Comics

The feeling worsened by the moment, becoming a black dread, and by the time the Tokamak pulled to stop, his newborn heart was racing, and his quick damp breath tasted foul.
Three more cars pulled up behind him, including a Tokamak, and he happened to glance at the rearview screen when Blaine climbed out, walking with a genuine bounce, approaching on the right and rapping on the passenger window with one fat knuckle, then stooping down and smiling through the glass, proving that he had made a remarkable recovery since being murdered.
It had been opened, and the tokamak coils had been removed by some of the mandible-like manipulator waldos.
Fed by the energies of a tokamak larger than any other used so far in space and a lot of smaller communities on earth, it would hopefully create a fold in space and send us to another spot in our universe at a speed faster than light.
The tokamaks fed their power into a high-thrust ion drive, eight grid nozzles buried in a simple box structure that was fixed to the base of the ship almost as an afterthought.
