I talked about a drone for simplicity, and it makes sense that the "wings" push the air downward, but I wanted to know about a general case

I would like to build a drone. I was wonderingknow how much power I would need to keep it hoveringfor magnetic levitation.

$$P = Fv.$$

$F = F_g \approx \text{mass} \times 10$, okay. But $v = 0$! I can't believe I need no power to keep an object in the air. How does one explain this?
