Question

the images below show two pairs of magnets. the magnets in different pairs do not affect each other. all the magnets shown are made of the same material, but some of them are different shapes.
pair 1
pair 2
27.9 mm
46 mm
think about the magnetic force between the magnets in each pair. which of the following statements is true?
the magnitude of the magnetic force is smaller in pair 1.
the magnitude of the magnetic force is smaller in pair 2.
the magnitude of the magnetic force is the same in both pairs.

Explanation:

Step1: Analyze Magnetic Force Factors

Magnetic force between magnets depends on distance (inverse - related, roughly) and pole interaction (attraction/repulsion strength). Here, Pair 1 distance: 27.9 mm, Pair 2: 46 mm. Same material, so magnetic strength per magnet similar.

Step2: Relate Distance to Force

Since magnetic force (for similar magnets) decreases with increasing distance (greater separation means weaker force). Pair 2 has larger distance (46 mm > 27.9 mm), so force in Pair 2 is smaller.

Answer:

The magnitude of the magnetic force is smaller in Pair 2.
