   The energy of a density field is ((B_0)^{2}) / (2\mu). I am looking for a direct formula as such linking these two. Lets say I have the value for density of energy, how can we find the magnetic force?

   Solve the energy density for B. Then substitute that into the expression for F. Note, you will only be able to solve for the magnitude.
