I'm trying to build a circuit that uses a MOSFET fullbridge driving a LC parallel tank circuit (with a smaller inductor in series to smooth current).
The main inductor is an air coil whose magnetic field is supposed to be picked up by another resonant LC.
I'm in doubt in how to maximize the magnetic field strength for a given DC input voltage (12V) and oscillator resonant frequency. Right now I'm using 375uH and 4.7nF, i.e. around 120kHz resoncance frequency.
I'm aware that increasing the number of turns should increase the magnetic field too, but it will also lower the quality factor...
How can I find the best combination of inductor and capacitor value?
