This is the most fun homopolar moto I've ever done r, the magnet car. I found the right combination of battery, total weight and magnet power. The acceleration and speed are so high that the rotor slides on the aluminum foil due to centrifugal force.
For those who do not yet know this experiment it is an homopolar motor. The battery is short-circuited. The magnetic field of permanent magnets and the magnetic field generated by the current passing from the tin foil interact, causing the rolling of the battery

On my channel you will find all the ways to have fun with magnets divided into 3 main categories:

Classical magnetic experiments such as magnetic levitation, homopolar motors, small magnetic weapons, Gauss cannons, gears, magnetic field viewers and much more.

Satisfaction video like the construction of magnetic sculptures, slime and magnetic putty and product review.

ASMR relaxing videos to watch but above all to listen preferably with stereo headphones to be able to appreciate the particular sounds of the magnets

About Magnetic Games:
All ways to have fun with magnets.

The magnetism has always intrigued me. The strength of the magnets is scientifically explainable but there's something "magical" about its interaction with the world. My Channel offers you curious experiments and fun games to do with magnets.
