SUMMARY
The homemade DC motor project involves two neodymium magnets, an aluminum split ring, and alligator clips connected to a 9V battery. Key issues identified include the necessity for opposite polarity in magnets, sufficient coil turns or current to generate strong magnetic fields, and the importance of a reliable connection between copper wire and aluminum. Additionally, the rotor's mass must be adequate to maintain motion during power interruptions.
