Silly me, I always thought that DC (as in the "DC Voltage" applied to the spheres in this experiment) stood for Direct Current...
They used DC to charge the spheres. After they were charged, their charge was static. A static charge has no flow of current. The right-hand rule applies to a current flowing along a conductor.

While "a [Direct Current] DC voltage was applied to the spheres they began to rotate until the stiffness of the suspending wires prevented further rotation."
