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 depends on the distance between them and their magnetic properties. For magnets of the same material, the closer the distance, the greater the magnetic force.

Step2: Compare distances

In Pair 1 and Pair 4, the distance between the magnets is 0.45 cm. In Pair 2 and Pair 3, the distance between the magnets is 0.75 cm. Since 0.45 cm < 0.75 cm, the force in Pair 1 and Pair 4 is greater than in Pair 2 and Pair 3.

Step3: Consider magnetic - pole alignment

In Pair 1, the poles are arranged in a way that the magnetic field lines have a more direct path between the poles compared to Pair 4. This results in a stronger magnetic - force in Pair 1.

Answer:

Pair 1
