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: Determine the factors affecting magnetic force

The magnetic force between two magnets depends on the distance between them and their magnetic strengths. Magnets made of the same material - larger magnets have stronger magnetic fields. And the closer the magnets are, the stronger the magnetic force.

Step2: Analyze each pair

• Pair 1: Small distance (6.4mm) but relatively smaller magnets.
• Pair 2: Large distance (15.8mm) - magnetic force is weaker due to the inverse - square - like relationship with distance (even though magnets are larger).
• Pair 3: Large distance (15.8mm) - magnetic force is weaker.
• Pair 4: Small distance (6.4mm) and relatively larger magnets (compared to Pair 1).

Answer:

Pair 4
