7. ### How to calculate inductance?

You didn't ask about this but mu=muo*mur where muo=4 pi e-7 and mor is the relative permeability. The gauge of wire doesn't matter as far as the inductance is concerned. It does matter for the power dissipated.

8. ### Calculate the energy stored in the magnetic field if the permeability of the core is 500.?

Energy is .5 muo mur B H volume. If you know H and mur, you can easily compute the energy (assuming the core does not saturate). To determine the current use N=H length/currrent
