Magnetorotational instability

In addition to hydrodynamical forces such as pressure and gravity, an element of magnetized fluid also feels the Lorentz force $\backslash boldsymbol\; J\backslash times\backslash boldsymbol\; B\backslash \; ,$ where $\backslash boldsymbol\; J$ is the current density and $\backslash boldsymbol\; B$ is the magnetic field vector.

This induced electric field can now itself induce further changes in the magnetic field $\backslash boldsymbol\; B$ according to Faraday's law,
