The correct Answer is:
To solve the question regarding the Earth's magnetic field and its orientation relative to the geographic poles, we can break down the solution into the following steps: ### Step 1: Understand the Earth's Magnetic Field The Earth behaves like a giant magnet with a magnetic field that has a specific orientation. The magnetic field lines emerge from the magnetic south pole and enter the magnetic north pole. **Hint:** Remember that the Earth's magnetic field is similar to that of a bar magnet, with a north and south pole. ### Step 2: Identify the Geographic and Magnetic Poles The geographic poles of the Earth are the points where the Earth's axis of rotation meets its surface. The magnetic poles, however, are where the Earth's magnetic field is vertical. The magnetic north pole is not located at the geographic north pole. **Hint:** Geographic poles are related to the Earth's rotation, while magnetic poles are related to the Earth's magnetic field. ### Step 3: Determine the Angle Between the Geographic and Magnetic Poles The angle between the geographic north and the magnetic north is approximately 11.5 degrees. This is known as the magnetic declination. **Hint:** Keep in mind that the angle of declination can vary depending on your location on Earth. ### Step 4: Analyze the Orientation of a Suspended Magnet When a magnet is freely suspended, it will align itself with the Earth's magnetic field. The north pole of the magnet will point towards the magnetic north pole of the Earth, while the south pole of the magnet will point towards the magnetic south pole. **Hint:** A suspended magnet always aligns itself with the magnetic field lines, pointing from magnetic south to magnetic north. ### Step 5: Conclusion Thus, if we consider the orientation of a magnet suspended in the Earth's magnetic field, it will point from the magnetic south to the magnetic north. Therefore, the correct answer to the question is that the magnetic field points approximately from the geographic south to the geographic north. **Final Answer:** The magnetic field points approximately from the geographic south to the geographic north.
