There are six identical, circular, metal rings centered on the faces of a cube. Their diameters are equal the side lengths ’a’ of the cube. They all have equal currents ’I’ running through them. How must the currents run (maybe a picture would help) in order to generate the biggest B field at the center of the cube, and how large is that field?
