How would a bar magnet orient itself relative to this planet's magnetic field?
Maksim231197 [3]

The magnet's north pole would point to the Earth's south pole and the magnet's south pole would point to the Earth's north pole.

<u>Explanation</u>:

  • There is a magnetic pole in the earth and the magnetic poles of the earth run using the equator and it has both the closures at the arctic pole and the Antarctic pole. The attractive positive field or the north pole is situated in the arctic zone and the south pole is situated in the Antarctic zone.  
  • The magnetic positive field or the north pole is situated in the arctic zone. Any magnet which is allowed to rotate whenever suspended on the outside of the earth will align itself with the magnetic field of the earth. That is the way the bar magnet orients itself comparative with this current planet's magnetic field.
