    It would probably be quicker for you to look it up yourself because the answer is complicated to explain. But it’s an electromagnet made from superconducting materials, and that is why it seems to violate your common sense.

      Others explained it fairily ELI5 in this thread, thanks.
      It’s not just an electromagnet is the TL;DR.
