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 it
they used 50 coils of wire around bigger nails
