The momentum equation for an electrically neutral, conducting, nonpermeable fluid has the form (Jackson, 1962):

ρdvdt=−∇p+J×B+Fv+ρgρdvdt=−∇p+J×B+Fv+ρg

where FvFv is the viscous force, which in the Navier-Stokes momentum equation is usually written in terms of the stress deviator tensor ττ:

Fv=∇⋅τFv=∇⋅τ

What is the corresponding form for an electrically non-neutral, permeable fluid?

I am particularly interested in the case of a permeable material. I expect that in this case the magnetic field HH should appear in the equation instead of the magnetic induction BB.

References from book/articles are much appreciated.
