Consider a particle in between two rings which have a potential difference across them. How do u find the potential at any point in between the two rings which could be off axis? Once i find potential , how can i find electric field?

Hi. This is a tough one. (Probably why no one has tried to answer it.) First an observation. At the Museum of Science in Boston they have a device that looks like a plate of metal 4 inches in diameter. It has a 1 inch hole at its center and fits over a vertical rod about 6 feet long. When you press a button a current passes through the base and causes the ring to jump up several feet. This is most likely caused by an induced current in the ring that 'pushes' off the current in the base. They are NOT perfectly concentric, as in your example. As a result a random distance passes before the ring ID touches the rod and causes it to stop. As to how to calculate the actual force, I'm at a loss. If they were concentric then the fields would be shaped like a torus. The calculation would be similar to two planes. Off center the fields would exert a distorted force. If you find a solution I would love to see it!
