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 greatest magnitude. pair 1 pair 2 pair 3 pair 4 submit work it out

Explanation:

Step1: Analyze the factors affecting magnetic force

The magnetic force between two magnets depends on the size of the magnets (larger magnets generally have stronger magnetic fields) and the distance between them.

Step2: Compare the pairs

• Pair 1: Smaller magnets and larger distance.
• Pair 2: Larger magnets (compared to Pair 1) and larger distance.
• Pair 3: Larger magnets and smaller distance (15.8mm).
• Pair 4: Smaller magnets (compared to Pair 3) and smaller distance.

Since Pair 3 has larger magnets (stronger magnetic fields) and a relatively small distance, the magnetic force magnitude is greatest.

Answer:

Pair 3
