BIO 161: Scientific Method Help - Determine Variables

[numberrronee]

I need to find out if I am right? I am in BIO 161 and need help answering these questions.

Sara and Michael tested electromagnets to see if the size of wire they used would make the magnets stronger. They selected 6 steel nails of the same size to make the magnets. Using 6 different sizes of insulated wire, they put 50 turns around each nail. Then each nail was hooked to 2 D cell batteries to make electromagnets. The strength of each magnet was tested by counting the number of paper clips which could be picked up by the electromagnet.

Determine

independent variable - (by counting)
dependent variable - (insulated wire or nails)
experimental group - (magnets)
control group - (paper clips)
controlled variables - (nails) (can be more than one)

are these answers right?

i think their pretty much one word answers. when we did an example they were just one word answers.

thanks a lot

independent variable - (by counting wire gauge)
dependent variable - (insulated wire or nails number of paper clips)
experimental group - (magnets)
control group - (paper clips N/A)
controlled variables - (nails) (can be more than one wire gauge)

are these answers right?

No.
