Ms. Owens' class is studying magnets. Ms. Owens showed her students how to make an electromagnet using a nail, a
D-cell battery, and plastic coated wire. The students wrapped the wire around the nail and then attached the ends to
the battery. When they were finished, they tested their magnets by trying to see how many paperclips their magnets
could pick up. They also tested whether they could increase the strength of their electromagnets by using more coils
of wire. They recorded the class average of their results in the data table seen here. Review the students' data. Predict
how many paper clips the students would pick up if they used 50 coils of wire around bigger nails.
