This type of homopolar motor can be made in an infinite number of configurations, proportions and dimensions. Lithium batteries are perhaps too powerful and tend to melt the copper wire if it is too thin, I suggest you try with normal rechargeable batteries.
These are the magnets I used for this video, thank you supermagnete.com for giving them to me for free

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.
