If it's the same Inverse Square Law as applies to lighting (could there be two?) the effect would be one quarter the magnetism at twice the distance, or, put another way, if you double the distance you get 1/4 the effect.

This is because the light (or magnetism, or...or...) is not only spread horizontally, but vertically as well.

Since everybody here likes photos and I had 20 mins. between appointments, I drew a diagram!
