How it works

What this project is testing.

Levitation is not anti-gravity; it is force balance. Gravity pulls down while magnetic forces push or pull upward.

The experiment demonstrates how magnetic fields can act at a distance, and why stable levitation usually needs careful geometry, feedback, or changing fields.

F_{ma g} = m g

At hover, the upward magnetic force balances the object weight.
