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 weakest magnetic force.

Explanation:

Step1: Understand the factors affecting magnetic force

The magnetic force between magnets depends on two main factors: the distance between the magnets and the size of the magnets. Larger magnets have stronger magnetic fields, and the closer the magnets are, the stronger the magnetic force.

Step2: Analyze each pair

• Pair 1: Distance is \(14.4\) mm.
• Pair 2: Distance is \(23.1\) mm.
• Pair 3: Distance is \(14.4\) mm, but one magnet is larger (stronger field).
• Pair 4: Distance is \(23.1\) mm, and one magnet is larger (stronger field).

Since Pair 2 has the largest distance (\(23.1\) mm) and no indication of larger - than - average magnet size (compared to Pair 4 where one magnet is large), it will have the weakest magnetic force.

Answer:

Pair 2
