Resonance is good if it accelerates something nearby. In any case, a resonant circuit is an oscillation of the amount of energy between the coil and the capacitor. If we approach quantitative expression, then instantaneous power can be expressed roughly: Pr = UI = 12*1 = 12W. Let us assume that the oscillation frequency in the circuit is 400 Hz to express how much power in 1 second Pr = UI *(1/f) = 12 W *(1/400) = 0.03 W provides the creation of a field in the coil. You can simply organize the rotation, but doing the work and overcoming the braking of the shaft by an opposing force, for example, the electromagnetic torque of a generator, will require precise calculation. The resonance will constantly break down when the load changes, since the rotation of the shaft must correspond to the oscillation frequency of the coil and the LC circuit. Theoretically, this is possible, but practically everything is not so rosy.
It will not be possible to remove 12W power directly from the resonant circuit, since in fact the cat cried there.
