Helmholtz coil design !!?

I'm trying to build a Helmholtz coil which is in parallel with a capacitor. I need to supply this circuit with an AC current with the frequency of 500 KHz and maximum voltage of 200 V (or more). The radius of the coils and the distance between the coils are considered to be 30 cm (0.3 m). With this info in hand, I need to know how many turns would I need to have in each coil ? What would be the Inductance of this Helmholtz coil ? What capacitor should I use in order to have resonance in frequency of 500 KHz ? and what would be the heat created in the process of running this setup for one hour !!??
