Hi guys,

So far I am aware of these rules regarding magnetic fields/direction of current:

A compass needle point is attracted to a south pole (or inversely repelled by a north pole).

Left hand rule #2: For an electromagnet, point thumb toward north pole, fingers curl in direction of current (up or down the front).

However there is a diagram I've been looking at for some time and I can't figure out how it's possible! I have the answer I just can't work in reverse to try to discover this rule: what effect does moving a permanent AWAY from an electromagnet, with its north pole closest to the electromagnet, regard current direction, and compass deflection (compass placed on the opposite side).

I've attached an image of the diagram with the answer included (multiple choice, it has a check by it).

Thanks,

Mike.
