A student uses two magnets to pick iron screws out of a pile of scraps. Would more magnets attached to the top of the first two magnets help the students find the screws Easier? Why or why not?

When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.

The answer would be dogs.
