The linear motor rotates an aluminum pipe when current is applied to the rails.
The direction of movement will change according to the polarity of the magnets and the current!

When you apply current to the rails, you can see the aluminum pipe rotate using electromagnetic power. By constructing both the generator and the linear motor, you can enjoy learning how current, magnetic fields, and electromagnetic force interact to create motion.
