The battery and the magnet spin because of a tangential force created by the flow of a current through the magnet. The magnitude of the force is given by the product of the current, I, the length, L (which, in this case, equals the radius of the magnet), and the magnetic field strength, B.
The magnets have been carefully aligned so the force on both magnets points in the same direction, and the result is that the magnets and battery move. But as they move, the magnetic field moves with them and you get a constant motion.
In order for the battery and magnets to move, there has to be a force acting on them. The force that causes the battery and magnets to move results from the interaction of the magnetic field produced by the magnets with the current that flows through the wire, the magnets, and the battery as the wire touches the magnets.
In an investigation recently published in Nature Energy, scientists demonstrated the ability to use a magnetic field to align graphite flakes within electrodes as they're manufactured. The alignment gives lithium ions a clearer path to transit the battery, leading to improved performance.
Center the magnets. Touch the tip of the screwdriver to the single magnet attached to the positive pole of the battery. Hold the battery up so that the battery and magnets are hanging from the screwdriver. Touch the free end of the copper wire to the lower stack of batteries. Touch the magnet in the stack that is closest to the battery.
The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets. The magnets have been carefully aligned so the force on both magnets points in the same direction, and the result is that the magnets and battery move.

The Impact Of Magnets On Batteries: Exploring The Relationship
Magnets Erase Battery Memory: In the context of rechargeable batteries, the term "battery memory" refers to a phenomenon observed in older nickel-cadmium (NiCd) batteries. It is caused by partial charge and discharge cycles. Magnets, however, have no effect on erasing or altering battery memory. Modern lithium-ion batteries, which are widely used …
