Question

the images below show four 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 sizes and shapes. think about the magnetic force between the magnets in each pair. select the pair with the magnetic force of greatest magnitude.

Explanation:

Step1: Recall magnetic - force principle

The magnetic force between two magnets is inversely proportional to the square of the distance between them and also depends on the magnetic strength of the magnets. Since all magnets are of the same material, the key factor here is the distance.

Step2: Compare distances

We have four pairs of magnets with distances: Pair 1 has a distance of 14.2 mm, Pair 2 has a distance of 23.4 mm, Pair 3 has a distance of 25.4 mm, and Pair 4 has a distance of 14.3 mm.

Step3: Determine the pair with the greatest force

The pair with the smallest distance will have the greatest magnetic - force magnitude. Among the given distances, 14.2 mm (Pair 1) is the smallest.

Answer:

Pair 1
