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 number of loops (or coils) of wire affect the strength of the electromagnet? 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 distance between the electromagnet and the metal objects affect its strength?

Explanation:

By observing the two set - ups, the battery and type of wire seem to be the same, and the distance between the electromagnet and metal objects is not the focus. The main difference is the number of loops of wire around the nail. So the question being tested is likely about the effect of the number of loops on the electromagnet's strength.

Answer:

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