My new program "newpotmag.f90" solves the magnetic induction equation in terms of

We then calculate the modulus of

I used my IDL program "iso.pro" to plot the results obtained at time t=0.00, t=0.02, t=0.04,....t=0.1

I opted to graph the results at the isosurface level 0.6 as this gave reasonable results throughtout the whole time period.

I ran my Fortran program with

As we can see below, the results are identical to those that we saw in the steady flow case. This suggests that the program is working correctly.
