How Do You Make A Simple Little Motor (A Great Project For Learning About Electricity)?
The beauty of this project is its simplicity. Making this motor will show you the basics of how a motor works. All you need are a few cheap household items. This project is great for kids or anyone interested in playing with electromagnets to see how they can be applied in the real world. The wire coil you make functions becomes an electromagnet when the sanded-sides of the wire touch the paperclips, thereby completing the circuit. When electricity flows through the coil, there is a magnetic field as long as there is an electric current. When the coil becomes an electromagnet, it’s magnetic field interacts with the magnet below it and it wants to turn toward it. When the coil loop turns over, the side with enamel on it blocks the flow of electricity. The “on-off” is what keeps the momentum going, otherwise the coil would stay motionless. To see this phenomenon in action, you can make your own little motor. Here’s how you do it: Bend each of the paperclips so that one end is a straight
