A group of students were experimenting with building electromagnets in science class. To do this, the
students wrapped a piece of insulated copper wire around an iron nail and then connected the two ends of
the wire to a battery, making the nail magnetic. The number of wraps of the wire around the nail affected the
number of metal paperclips that the electromagnet could pick up at one time. The results of the students’
experiment are shown in the data table below. Predict how many paperclips the electromagnet would have picked up if the students had wrapped the wire
around the nail only five times.
