Thank you, but the instructions you had included: "if the north needle points to it then it is negative like the north pole" do not work with the magnets I have bought, and seems that still compass is needed to figure out north even if we then wish to go with positive/negative as you suggest. The shape of magnets that would be useful to me is flattish, for example a flat disk. "pointing the compass toward the magnet" doesn't give me anything consistent as to which side of the magnet is north. Holding one side of the magnet's flat side near the compass sometimes gives me the same result on the compass as holding the other side of the magnet toward the compass.
