How to use batteries, magnets, cans of aluminum belt to make a rotating aluminum belt device, please explain
Attract aluminum cans with magnets to make them turn It seems impossible, and we know that magnets can only attract iron, cobalt, nickel and their alloys, and will not attract aluminum products. But the device we built below successfully realized this impossible function.
The middle part of the penholder is fixed with 2 high strength magnets. When we turn the magnet, we can turn the cans on the left to rotate together.
On the left is an aluminum can top. It is on a vertical shaft and can rotate freely. On the right is a used water pen holder, the same on the vertical shaft, you can freely rotate.
