the north pole of a compass is attracted to the north magnetic pole of the earth, yet like poles reple. can you resolve this apparent dilemma?

  • physics - ,

    The needle end that points north gets labelled N, but its polarity is really opposite.

  • physics (correction) - ,

    When one defines a magnet's N-S polarity in terms of the direction of the field lines that emerge, the compass needle is correcly labelled, but one finds that the north magnetic pole of the Earth is actually a south magnetic pole, and vice versa.
