Magnetism basics — identifying a magnet’s south pole: Which statement correctly describes the south-seeking pole of a bar magnet with respect to the Earth and other magnets?
-
Athat would be attracted to the earths north magnetic pole
-
Bthat has its molecules arranged in a random pattern
-
Cthat would be attracted to the earth's south magnetic pole
-
Dthat would be repelled by the north pole of another magnet
-
ENone of the above
Answer
Correct Answer: that would be attracted to the earths north magnetic pole
Explanation
Introduction / Context:This question complements the common discussion of a magnet’s north pole. Here we consider the south-seeking end. The Earth’s magnetic labeling can be confusing: near the geographic South, the planet behaves magnetically like a north pole, attracting a magnet’s south pole.
Given Data / Assumptions:
- Standard bar magnet with defined north and south poles.
- “South pole” means the end that seeks geographic South.
- Earth’s geographic South corresponds to a magnetic north polarity region.
Concept / Approach:Magnet interactions: unlike poles attract; like poles repel. The Earth’s geographic South is associated with a magnetic north region. Therefore, a magnet’s south pole will be attracted toward that area. Between magnets, a south pole attracts a north pole and repels another south pole.
Step-by-Step Solution:Identify Earth’s effective polarities: geographic South ≈ magnetic north region.A magnet’s south pole is attracted to magnetic north.Hence, it is drawn toward the Earth’s north magnetic pole (near geographic South).Therefore, statement (a) is correct.
Verification / Alternative check:Compass logic reversed: the south-seeking end points toward geographic South because it is attracted to magnetic north, confirming the polarity relationship.
Why Other Options Are Wrong:(b) Random domain orientation describes a demagnetized material. (c) Attraction to Earth’s magnetic south would attract a magnet’s north, not its south. (d) A south pole is attracted to a north pole, not repelled.
Common Pitfalls:Confusing geographic with magnetic labels; forgetting that attraction occurs between unlike poles.
Final Answer:that would be attracted to the earths north magnetic pole.
