Say I have a bunch of round magnets. Cylindrical. O want to combine them into a sing donut shape arrangement. Which arrangement gives the strongest attraction to a piece of metal plate?

NSNSNS or NNNNNN?

N is north and S is south.

You can buy ring magnets. If you are playing with magnets, maybe check out John Bedini and his SG machines.
