We were having a discussion about magnetic monopoles in an AP Physics course a while back, talking about why they can't happen, etc. One of the other students (there were 7 of us, haha) said, "What if you magnetize a bunch of needles and then stick, say, all of the south poles into a styrofoam ball. Wouldn't this act like a magnetic monopole?" Even though this probably isn't possible, we, including the teacher, couldn't find a reasonable solution as to why it wouldn't act like a monopole. Any suggestions/solutions as to why it wouldn't act as a monopole? Thanks!
