An LR circuit, driven by an oscillating voltage (most important), will have a resonant frequency:
Resonance - Wikipedia, the free encyclopedia

To get resonance, either the component values are changed or the driving voltage is changed so that the frequency of your oscillator is correct for the rest of the circuit.

If there is a second circuit, possibly arising from the other coil of a transformer, then the second circuit must resonate at the same frequency as the first.

I think this is correct. But there are plenty of people on this board who know a thousand times more about this than I.
