Are the north magnetic pole of the earth and the north pole of a bar magnet of the same polarity? Please Explain. I don't seem to understand the question.

  • $\begingroup$ @UKH - "polarity" has nothing to do with strength, and everything to do with the direction of the magnetic field lines. $\endgroup$ – Floris Feb 14 '17 at 22:24
  • $\begingroup$ @Floris yeah, my bad. I misunderstood the question. I thought OP is having doubt with pole strength. Just got confused with polarity and pole strength. I raised a question about that in the comment. $\endgroup$ – UKH Feb 15 '17 at 3:01
  • $\begingroup$ @UKH no need to apologize- your comments were confusing because you were confused. Happens to all of us. $\endgroup$ – Floris Feb 15 '17 at 3:10

No. The earth's North Pole is a "magnetic south pole". With a compass, the part of the needle that points north is a magnetic north pole. With magnets, opposite poles attract, so what we call North on the earth must be magnetic south to attract the needle's north.
