Fluctuations of electrical conductivity: a new source for astrophysical magnetic fields [PDF]

open access: yes, 2016
We consider the generation of magnetic field by the flow of a fluid for which the electrical conductivity is nonuniform. A new amplification mechanism is found which leads to dynamo action for flows much simpler than those considered so far.
