Force Free Equilibria

In this example we solve the so-called force-free equations. They are just like the ordinary MHD equations, but without a pressure term. In that sense this example is similar to the Burgers Shock, except that here we also have a magnetic field.

Determine, as a function of time, the degree to which the field is force-free.

How close to a constant α (linear) force-free field is it?

At the moment the field is decaying. We can try other boundary conditions.
