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. pair 1 pair 2 s n n s s n n s 3 in 1.25 in 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 greater in pair 1. the magnitude of the magnetic force is greater in pair 2. the magnitude of the magnetic force is the same in both pairs.

Explanation:

Step1: Recall magnetic - force principle

The magnetic force between two magnets is inversely proportional to the square of the distance between them (for simple cases).

Step2: Compare distances

In Pair 1, the distance between the magnets is 3 inches. In Pair 2, the distance between the magnets is 1.25 inches. Since 1.25 < 3.

Step3: Determine force magnitude

As the distance is smaller in Pair 2, the magnetic - force magnitude is greater in Pair 2 according to the inverse - square relationship.

Answer:

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