- We used K&J magnetic website to obtain force to distance data
- One caveat was that we could not get data for a disk magnet repelling a ring magnet. So we plotted Disk on Disk and Ring on Ring using two term exponential regression, we added our own required theoretical repulsive force required.
- If the repulsive force was between the other lines, it was viable.. Because the force of the disk v ring would be somewhere between them.
