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. think about the magnetic force between the magnets in each pair. select the pair with the magnetic force of greatest magnitude.
Answer
# Explanation:
## Step1: Recall magnetic - force principle
The magnetic force between two magnets is inversely proportional to the square of the distance between them and directly proportional to the magnetic strength (which is related to size here as they are of the same material). Larger magnets and smaller distances result in greater magnetic force.
## Step2: Analyze each pair
Pair 1 and 4 have a distance of 31.8 mm, while Pair 2 and 3 have a distance of 16.8 mm. Among Pair 2 and 3, Pair 2 has larger - sized magnets.
# Answer:
Pair 2
