Its rather a simple question. But i'm still confused. the north-pole of a free suspending magnet points to the north pole right? My chemistry teacher said that the north pole of the magnet is actually the south pole and thus it is attracted to the north pole. The physics (which is a more credible source) says that the north pole points to the north due the the magnetic field lines (they move from south to north) I find both possible. But they clash. X.X which 1 is it?  A friend of today is an enemy of tomorrow. I am an empty shell. I don't feel loved at all |

(I'm in eigth grade so don't expect me to give you the right answer :) They say that the Geophysical North Pole is the same as the Magnetic South Pole so a free suspending magnet's North pole will be attracted to the Geophysical North pole. |

Using the model of field line from electromagnetism, the field lines are defined as lines that point from south to north with arrows point toward the north. A magnet sitting in the Earth's magnetic field would have the field lines aligned so that the south pole of the magnet is point to the north. This is because the field lines are coming out of the south pole of the magnet and the field lines must end by going into a north pole. In this case, it is the north pole of the Earth.  |
