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.\npair 1\npair 2\nthink about the magnetic force between the magnets in each pair. which of the following statements is true?\nthe magnitude of the magnetic force is greater in pair 1.\nthe magnitude of the magnetic force is greater in pair 2.\nthe magnitude of the magnetic force is the same in both pairs.
Answer
Explanation:
Step1: Recall magnetic - force principle
The magnitude of the magnetic force between two magnets depends on the pole - polarities and the distance between them.
Step2: Analyze distances and polarities
In both Pair 1 and Pair 2, the distance between the magnets is 45 mm. Also, in Pair 1, the facing poles are N - N and S - S (repulsive), and in Pair 2, the facing poles are N - S and S - N (attractive). But the magnitude of the magnetic force is determined by the inverse - square law of magnetic forces and only depends on the pole strength and the distance between the poles. Since the materials are the same (so pole strength is related in the same way for both pairs) and the distances are equal (45 mm in both cases), the magnitude of the magnetic force is the same in both pairs.
Answer:
The magnitude of the magnetic force is the same in both pairs.
