Motors

In our first experiment we demonstrated magnets and power by putting a coil of wire around a straw. We then striped the ends of the wire and held them to the opposing ends of a battery. Then we placed a straight pin in the straw, It was immediately sucked into the middle of the straw. The coil heated up and so did the needle. I think this is because of the electromagnetism between the wire pin and battery. The battery made the wire more magnetic. The second experiment we did was with the circle of wire magnet 2 Safety pins and magnet. when put together in te correct fashion it will make the circle spin and flip around.
