.... the current into whichever solenoid is touching it (solenoid 2 or 3). When part 5 spins, the direction of the current through 2 and 3 are reversed every time the motor spins half way around. The metal pieces touch the solenoids in just the right places to give solenoids 2 and 3 a magnetic field that attracts 1 and repels 4 and visa versa. The end result is that as 2 or 3 approaches 1 or 4, it is given a magnetic field that is opposite to that of 1 or 4. Therefore, the two are attracted to each other. As the moving solenoids line up with the other solenoids, the metal things on top of 5 reverse the current. That means that 1 and 4 now repel th ....
