A sawtooth is a magnetic [[reconnection]] phenomenon occurring in many [[tokamak]] plasmas.
The name is due to the characteristic [[Wikipedia:Sawtooth wave|waveform]] of many diagnostic signals.

The reconnection leads to the rapid expulsion of energy from a central region (usually contained with the ''q'' = 1 rational surface).
This leads to the fast increase of energy content in an annular region surrounding the central region.
