Since our paper ones are on Monday, I've decided to upload a picture explaining a simple analogy that you can use for attraction/repulsion of wires with current flowing through. It was a question in the June Physics 2007, and I know that there are people who do not understand the principle.

So erm... here it is!


Red lines indicate direction of force. Sorry about the crummy drawing. I did in in Paint for Daniel last night. Just thought it would be good to share, just in case. Hope it helps =)

EDIT: The picture didn't load completely. Used in-built uploader instead. It's smaller, but still readable(I hope).
