I found a question on the forum:

The task. There is a neodymium. very much. I would like to use only the South Pole for one task.
I broke my head like I cut it in half.
Magnet is thick.
Who will advise?

Do you think trolling? And the Nifiga, the people on the full seriousness of 70 posts discussed how to cut than to cut. The obvious idea that there would eventually be two magnets was heard only three years later. This is PPC.
