If we can assign an inductance and current value to the contents of a permanent magnet, we can coservatively calculate the energy in a permanent magnet according to the equation<http://en.wikipedia.org/wiki/Superconducting_magnetic_energy_storage#Calculation_of_stored_energy> : E = L*I^2/2 How might we go about assigning L and I values given a specific magnetism?
