Can you generate electricity while magnetically levitating at the same time?
Yes — Papa Bale demonstrates exactly this. With coils positioned adjacent to the magnets on levitating discs, the changing magnetic flux as the disc moves or spins induces a current in the coil. The multimeter confirms live voltage output while the disc is simultaneously in a levitated state. Related terms: levitation and electricity demo.
Why does flipping disc polarity help achieve levitation?
Flipping the polarity of a disc changes which face presents north or south to the disc below it. To achieve stable levitation (repulsion), opposing faces must present the same pole — both north or both south facing each other. Flipping a disc that was previously attracting its neighbor converts it from attraction to repulsion, enabling levitation. Related terms: coil output during levitation.
How are the coils positioned relative to the magnets in this demo?
The coils are placed adjacent to the magnets on the stacked discs — close enough to sit within the magnetic field but not touching the disc surface. As the disc rotates or oscillates during levitation, the changing magnetic flux through the coil induces an EMF, measurable with a multimeter. Related terms: stacked disc polarity flip.
What is polarity flip in pulse motor experiments?
