The process of building an electric motor.

Materials: battery, cup, plastic-foam, magnet, paperclips (2), sandpaper, permanent marker, tape, tube, and wire, insulated, with alligator clips.
Step 1: Wrap the coil around a circular tube; turn the wire into a coil, leaving about 5cm of free wire on each end.
Step 2: Sand the free ends of the wires about halfway.
Step 3: Unfold 2 paperclips, but make a hook at the top.
Step 4: Place two magnets inside the cup, at the bottom and then turn it over on the outside and put it on the bottom of the cup, Leaving the cup placed down.
Step 5: Tap the paper clips to the side of the cup, should keep the coil from touching the magnet.
Step 6: Test the coil, slighty hit on side of the coil and see if it will spin . The should not be wobbly or sliding to one side.
Step 7: Make changes if it did not spin.
Step 8: Attach one end of the alligator clip to one of the paperclips.
Step 9: Attach the free end of the same wire to the battery.
Step 10: Do the same thing with the alligator clip to the other paperclip and to the other part of the battery. SPIN IT!!!!!!!!! Record your observations.
Step 11: Stop the coil, and spin it the opposite way. Record your observations.
Step12 : If the coil doesn't keep spinning, check to see if only the bare wire is touching the paperclips for the other half to rotate.
Step 13: If removed too much enamel, hust color some of it with the permanent marker.
Step 14: Switch the connections to the battery, and redue steps 10 and 11.

Building a DC motor.

The results after the experiment is that in our experiment we converted electrical energy into mechanical energy by connecting the wires to a bunch of things, and eventually the coil spun around and around, but when we tried to reverse the direction of the coil spinning it refused and spun back aorund the other way.
