Question

two students argue about why two magnets suddenly repelled each other during a test. student a thinks the magnets were too strong. student b thinks the magnet was flipped. which observation would most support student b’s explanation? the magnets move apart only when pushed together; the orientation of one magnet was reversed before release; both magnets had identical strength labels; the magnets repel at any distance

Explanation:

Student B claims the magnet was flipped, which changes its orientation so like poles face each other (causing repulsion). The observation that directly confirms the magnet's orientation was reversed before the repulsion occurs is the strongest support for this claim. Other options do not link to the magnet being flipped: repulsion only when pushed does not relate to orientation, identical strength labels do not address flipping, and repulsion at any distance is not tied to a change in orientation.

Answer:

B. The orientation of one magnet was reversed before release
