GK QUESTION#2963

Using the simplified school-level bar-magnet model of Earth and neglecting magnetic declination, which statements are correct? I. Away from nearby interfering magnetic fields, a freely suspended bar magnet aligns approximately north–south. II. Its north-seeking end points approximately towards geographic north. III. The region near geographic north is treated as a magnetic south pole in this model.

Answer

C. All three statements are correct

Show ExplanationHide Explanation

Explanation

In the simplified bar-magnet model, a freely suspended magnet aligns approximately along the magnetic meridian. Its north-seeking end points approximately towards geographic north, where Earth behaves like the south-seeking end of a bar magnet. Geographic and magnetic directions are not exactly identical in reality.
