The pole of a freely suspended magnet that orients toward geographic north is called its:
Anorth pole
Bsouth pole
Cmagnetic pole only
Ddomain
Answer & Solution
Correct answer: A. north pole
1. A bar magnet has two ends, and the one that consistently points toward geographic north defines a naming convention.
2. The text states: "orients northward is called the north pole, and the opposite pole of the magnet is called the south pole."
3. So by definition, the end that points north is called the magnet's north pole, and the opposite end is its south pole.
4. "Magnetic pole" alone and "domain" are not specific enough names for this particular end of the magnet.
