Taking a long piece of wire start to wrap it around a large steel nail (between 50 to 100 times). connect the free ends of the wire to a flashlight battery. This will create an electromagnet. To avoid depleting the battery, do not leave the wires connected for very long. Use a permanent magnet, any you have availabe will work, even a refrigerator magnet. Determine how close the permanent magnet mujst be to a steel paper clip ( or other small metal object) to make it move. Notice how close it must be to pick the object up. Record results. Repeat with an electromagnet. Compare your results and explain your concllusions.
