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 magnetic force of smallest magnitude. pair 1 pair 2 pair 3 pair 4

Explanation:

Step1: Analyze the factors affecting magnetic force

The magnetic force between magnets depends on the size of the magnets (larger magnets have stronger magnetic fields) and the distance between them. Smaller magnets and larger distances result in smaller magnetic forces.

Step2: Compare the pairs

• Pair 1: Larger magnet on the left, distance \(44.4\) mm.
• Pair 2: Larger magnet on the left, distance \(29.6\) mm.
• Pair 3: Smaller magnets, distance \(44.4\) mm.
• Pair 4: Smaller magnets, distance \(29.6\) mm.

Since Pair 3 has smaller magnets (compared to Pair 1 and 2) and a larger distance (compared to Pair 4), it will have the smallest magnetic force.

Answer:

Pair 3
