How to levitate a spinner: the power of magnets

Lesson in levitation

Get yourself 2 loudspeakers. Trash them!

Take out the circular magnets and build yourself a spinner AND LET THE MAGIC BEGIN!

The spinner seems to go on forever. Is this a Perpetuum mobile?

Can we get energy from it?

Nah, this is just a situation with very high yield. Because of the absence of friction. So the energy that was given to the spinner is conserved. Only little energy is lost through air friction.

Too bad for the believers of free energy 😦
