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. think about the magnetic force between the magnets in each pair. select the pair with the strongest magnetic force. pair 1 pair 2 pair 3 pair 4 submit work it out

Explanation:

Step1: Determine the relationship between magnetic force and magnet size and distance

The magnetic force between magnets depends on two factors: the size of the magnets (larger magnets can have stronger magnetic fields) and the distance between them (closer magnets have stronger forces).

Step2: Analyze Pair 1

In Pair 1, the magnets are relatively close (1.5 inches apart). Also, one of the magnets is large. Since opposite - poles (N - S) attract, and the distance is small with a large magnet, this pair has a strong magnetic force.

Step3: Analyze Pair 2

In Pair 2, although there is a large magnet, the distance between the magnets (3.5 inches) is larger than in Pair 1. According to the principle that magnetic force decreases with increasing distance, the force in Pair 2 is weaker than in Pair 1.

Step4: Analyze Pair 3

In Pair 3, the magnets are close (1.5 inches), but both magnets are small. Smaller magnets generally have weaker magnetic fields compared to larger magnets (assuming same material), so the force is weaker than in Pair 1.

Step5: Analyze Pair 4

In Pair 4, the magnets are far apart (3.5 inches) and both are small. The combination of large distance and small magnet size results in a very weak magnetic force.

Answer:

Pair 1
