Answer:
Option "D" is the correct answer to the following question:
Step-by-step explanation:
Magnets usually have their pulling properties, which we call magnetic power.
A major feature of magnetic power is that the closer the magnets are brought together, the higher the magnetic force increases.
On increasing distance, the magnetic force starts to decrease.
So, we can say that students should bring magnets closer to each other to increase the magnetic power.
