Q? New Gadgets For My Dream?

If the magnetic coil and heated coil at 7.498 Hz is a resonance phenomenon, then maybe adjusting frequency can fast adjust lift.  Changing magnet flux in a coil by changing current is limited by its inductive nature and temperature,  \(T\)  change with current is even slower.

Lift Frequency Response

Frequency response and the Q factor profile around 7.489 Hz is important.
