Materials Needed:
- 1 9V battery
- 2 paper clips
- 1 piece of copper wire (about 1 meter long)
- 1 piece of Styrofoam (about 1 inch thick)
- Scissors
- Glue
Instructions:
1. Create the Base: Cut a square or rectangular piece of Styrofoam that is approximately 1 inch thick and 3 inches wide. This will serve as the base for your motor.
2. Create the Electromagnet:
a. Take the copper wire and wrap it around one of the paper clips multiple times, leaving a few centimeters loose at one end. Ensure that the wire is tightly wound and has several layers to create a strong electromagnet.
b. Repeat this step with the second paper clip.
3. Attach the Electromagnets:
a. Glue the two paper clips with the copper coils securely onto the Styrofoam base, with the coils facing each other.
b. Position the electromagnets parallel to each other and ensure they are spaced about an inch apart.
4. Create the Rotor:
a. Take the loose end of the copper wire from one electromagnet and connect it to the loose end of the wire that is wrapped on the other electromagnet. These two wires will serve as the rotor of your motor.
b. Leave a small loop or turn in the center of the wires.
5. Attach the Rotor to the Battery:
a. Take the 9V battery and use a piece of tape or glue to attach one of the wires to the positive terminal (+) and the other wire to the negative terminal (-) of the battery.
b. Ensure the wires have good contact with the battery terminals.
6. Test the Motor:
- Once everything is connected, you should see the coils rotating due to the magnetic forces between the electromagnets and the rotor.
Additional Tips:
- You can adjust the speed and power of the motor by varying the number of coils on the electromagnets and the size of the battery.
- Experiment with different designs and configurations of the coils to optimize the motor's performance.
