Difficulty: Easy
Correct Answer: It would be attracted toward the Earth's south magnetic pole (near the geographic North)
Explanation:
Introduction / Context:
This conceptual question checks your understanding of how a magnet’s labeled north pole (the north-seeking pole) interacts with the Earth's magnetic field and with other magnets. It also touches on a common misconception: the region near the Earth's geographic North actually behaves as a magnetic south pole, which is why a compass’s north pole points there.
Given Data / Assumptions:
Concept / Approach:
Magnetic poles interact according to two rules: like repels, unlike attracts; and the Earth's magnetic "north" indicator is a bit counterintuitive—compass north is drawn to a magnetic south in the high northern latitudes. Therefore, the north pole of a magnet is attracted toward the Earth's magnetic south (near the geographic North). Between separate magnets, the north pole is attracted to another magnet’s south pole and repelled by its north pole.
Step-by-Step Solution:
Identify the magnet’s north pole as the “north-seeking” end.Recall that Earth’s geographic North hosts a magnetic south polarity region.Therefore, the magnet’s north pole is attracted toward the Earth’s magnetic south near the geographic North.Cross-check with magnet-to-magnet interactions: north attracts south, repels north.
Verification / Alternative check:
Hold a freely pivoted bar magnet: the north-seeking end points toward geographic North. This confirms that the region near geographic North must be magnetic south, consistent with electromagnetic conventions.
Why Other Options Are Wrong:
(a) Random magnetic domains would not produce a strong pole; magnets have aligned domains. (b) The Earth’s “north magnetic pole” phrasing is misleading—near geographic North, the polarity is effectively south. (c) A north pole is attracted to a south pole, not repelled. (e) Incorrect because one option is correct.
Common Pitfalls:
Confusing geographic labels with magnetic polarity; assuming the Earth’s “north magnetic pole” is a magnetic north in the strict physics sense; forgetting like repels and unlike attracts.
Final Answer:
It would be attracted toward the Earth's south magnetic pole (near the geographic North).
