The name of the game is resonance. Many years ago I built a coil
that was about 5 ft high and 2 1/2 in. diameter. It resonated about
500KHz. The coil itself has inherent capacitance and the inductance
can be determined from formulas found in elementary texts. The
actual frequency can be determined by applying a low level square
wave and measuring the ringing freq with a scope. Keep in mind that
this device is a transmitter and may be illegal and will no doubt
cause RFI in your neighborhood. Also, RF burns are nasty.
