Did you know that your cereal may be magnetic? Depending on the brand of cereal you enjoy in the morning, you’ll be able to see the magnetic effects right in your bowl. You don’t have to eat this experiment when you’re done, but you may if you want to (this is one of the ONLY times I’m going to allow you do eat what you experiment with!) For a variation, pull out all the different boxes of cereal in your cupboard and see which has the greatest magnetic attraction.

Think of the attraction as a signal with lines that spread out in all directions. Since the signal spreads out, only a few “lines” reach the other object. But when the object gets closer, more lines touch the object, which means there is more attraction.
An inverse-square law tells us that the farther away an object is from an something causing an effect, the less change can be observed in the object. The name “inverse square law” comes from the math formula, which tells us that the intensity is proportional to 1/distance2.
when the cereals got closer, how did the attraction increase? can you please explain more
what is inverse square law?
