Nate, James, Adrienne and I made a DC motor and generator.
We built the motor by first, coiling a piece of copper wire around whiteboard marker. We then pulled the wire off and tied the wire three times on each side of the coils. They had to be parallel so that the wires on the sides are straight. Next, we took a foam cup and put two magnets, one on top and on on the bottom. The magnet on the bottom was to hold the top magnet in place. Afterwards, we straightened two paperclips until the formed a ‘p’. We had to straighten it slowly so the paperclip would not break. Then, we put the paperclips on opposite sides of the foam cup. Finally, we scraped off the thin plastic layer on the wire and put the coil in the middle of the paper clips so that metal was touching metal. When we clipped the alligator clips onto the paperclips, the circuit was complete. So when we turned the transformer on, there was a magnetic field around the coil and because of the attraction and repulsion of the two magnetic fields, the coil spun.
After, we made the motor into a generator. In the DC motor, to create electricity, you made the coil have a magnetic field by connecting electricity to the paperclips. For the motor to become a generator, the generator doesn’t use electricity and instead, produces electricity. So to make our motor become a generator, we rolled the flat part of the coiled wired between our fingers and so the wire ‘spun’. Then, we attached the sticks of the volt meter to the paperclips but the sticks couldn’t touch the foam cup. After, we measured the number of volts the generator made which was electricity and could then be used. You could also move the magnet around to create a magnet field and create electricity but it would be much less efficient.
