Electric currents in parallel attract each other, as you can see here (watch it at MIT):

Two flexible wires are suspended vertically. The wires are connected in series or parallel to a 12 V storage battery. When the wires are connected in series and power is applied they will repel each other; when they are connected in parallel they will attract one another.

Understanding Birkeland currents is important to get a glimpse of what electric currents circulating through plasma are capable of.
