A simple homopolar motor

Step 5 Collabrating time...

Make sure that the wire sits on a dipple of the top of the battery and also make sure that the bottom of the wire is touching but can still spin. The wire has to spin freely with no or little friction to achieve maximun results. Callabrate it till it can spin and keep on spinning. Notice that the battery is ballancing on the magnets. The battery never moves nor the magnets, the wire will move rapidly by itself.
