It shouldn't make that much difference, especially if you run each in its own conduit. If it's Romex, you might want to keep them about 6" apart.

Do Coriolis forces apply to electromagnetic energy? That's a new one on me. Twisting the wire would help reject RFI, but I don't think Romex will twist enough to do that very well. People do twist separate insulated conductors before pulling them thru steel conduit. That's the best if RFI is a problem where you are. I've also pulled Romex thru conduit (I think because the Romex was on sale ;-)
