Hello and welcome to the world of the Homopolar Motor Project!


In this exciting endeavor, we combine the fascinating principles of electromagnetism and mechanical engineering to create a simple yet mesmerizing motor. Stemming from the groundbreaking work of physicist Michael Faraday, this unique motor design opens the doors to a world of hands-on experimentation, enabling STEM (Science, Technology, Engineering, and Mathematics) students to gain a profound understanding of essential scientific concepts while having a blast.

The Homopolar Motor Project allows us to explore the principles of engineering design. Experiment with various materials, shapes, and configurations to optimize our motor's performance. This hands-on approach fosters innovation and deepens our understanding of engineering concepts.

Through this Project, we'll unlock the secrets of science in a tangible and exciting way. we'll delve into Faraday's Law of electromagnetic induction, master the right-hand rule, and unravel the intricate relationship between electric currents and magnetic fields.

Supplies

What you need -

  • Insulated copper coil
  • AA Batteries
  • Neodymium Magnets
  • A cylindrical object like a marker for coiling

Step 1: Shaping the Wire

  • Bend the wire into a loose "U" shape, leaving one end slightly longer than the other.
  • The longer end will be used to make contact with the battery terminal, while the shorter end will be the wire that interacts with the magnetic field.


Step 2: Preparing the Wire From Top

  • Using sandpaper or emery cloth, strip off the insulation from both ends of the copper wire for about 1 cm.
  • Make sure the wire is clean and free from any debris or oxidation.
  • Take the longer end of the wire and securely attach it to the positive terminal of the cell battery.
  • You can use electrical tape or adhesive putty to hold the wire in place. Make sure the connection is firm and stable.


Step 3: Preparing the Magnet

  • Take the neodymium magnet and ensure it is clean and free from any debris or coatings.
  • Place the magnet on a flat surface.
  • Carefully place the wire on top of the magnet, ensuring that the shorter end is making contact with the surface of the magnet.
  • Ensure the wire is not touching the battery terminal or any other motor parts.
  • Let the longer end of the wire touch the negative terminal of the battery briefly, creating a connection.



Step 4: Done

  • If the wire doesn't spin or spin inconsistently, make sure the wire is making good contact with the magnet's surface. Adjust the position of the wire as needed.
  • Check the wire's length and shape. Experiment with different wire lengths and shapes to optimize motor performance.
  • Ensure the battery is fully charged, and the wire is clean and properly attached to the battery terminals.
  • In conclusion, this project offers an invaluable learning experience for everyone. Hands-on experimentation will give us practical insights into electromagnetism, enhance our problem-solving skills, and develop a deeper understanding of engineering principles.
