The best conclusion for this student's work would be:
c. The number of turns on an electromagnet does impact the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up an increasing number of pins.
a.The number of turns on an electromagnet does not determine the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up an increasing number of pins.
b.The number of turns on an electromagnet does not determine the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up less pins.
