describing the earths magnetic field\nthe earth has a magnetic field. if you were to use a bar magnet to represent the magnet causing the magnetic field, which representation would be correct?
Answer
Brief Explanations:
The Earth's magnetic field is similar to that of a bar - magnet placed at its center. The south pole of the Earth's magnetic field is near the geographic North Pole and the north pole of the Earth's magnetic field is near the geographic South Pole. Magnetic field lines emerge from the magnetic north pole and enter the magnetic south pole. So the bar - magnet representation should have the south pole of the bar - magnet near the geographic North Pole of the Earth.
Answer:
The second representation (where the bar - magnet has S near the top of the Earth and N near the bottom of the Earth as shown in the image) is correct.
