I pointed the south side of the compass at the monopole, and it changed
direction. I tried testing it with another permanent magnet, which
quickly began to vibrate, and tried to switch sides. (N/S)

Its a dipole, but with monopolar qualities. A south field is produced
(and only south) on the inside of the device, and only north on the
outside. I still think its useful though.

I don't have a superconductive ring.
