Query: Helicity fluctuation, generation of linking number and effect on
  resistivity   The energy of the stochastic magnetic field is bounded from below by a
topological quantity expressing the degree of linkage of the field lines. When
the bound is saturated one can assume that the storage of a certain magnetic
energy requires a minimal degree of topological complexity. It is then possible
to infer a connection between the helicity content and the average curvature of
the magnetic field lines. The random curvature induce random drifts leading to
an additional dissipation and modified resistivity.
