The Shafranov shift<ref>V.D. Shafranov, Atomnaya Énergiya '''13''' (1962) 521, [http://dx.doi.org/10.1007/BF01312317 Translated ''Equilibrium of a toroidal pinch in a magnetic field'', At. Energy '''13''', 6 (1963) 1149]</ref> is the outward radial displacement ''Δ(r)'' of the centre of [[Flux surface|flux surfaces]] with [[Toroidal coordinates|minor radius]] ''r'', induced by plasma pressure and the hoop force <ref>John Wesson, ''Tokamaks'', Clarendon Press (2004) ISBN 9780198509226</ref>.
Typically, the shift is linear <ref>J.P. Freidberg, ''Plasma physics and fusion energy'', Cambridge University Press (2007) ISBN 0521851076</ref> in [[Beta|beta (β)]], and it tends to be more important for [[Tokamak|tokamaks]] than [[Stellarator|stellarators]],
due to the fact that the magnetic configuration is largely or partly imposed externally in the latter case.
