Question

question it! study the image. it shows observations that were made using an electromagnet. select the question that is most likely being tested. how does the distance between the electromagnet and the metal objects affect its strength? how does the strength of the battery affect the strength of the electromagnet? how does the type of wire affect the strength of the electromagnet? how does the number of loops (or coils) of wire affect the strength of the electromagnet?

Explanation:

By observing the two images of electromagnets, the main difference is the number of loops (coils) of wire around the nail. The battery and wire type seem the same, and there's no indication of changing the distance between the electromagnet and metal objects. So, the variable being tested is likely the number of loops of wire.

Answer:

How does the number of loops (or coils) of wire affect the strength of the electromagnet?
