• Resumen

  • When I was about 10 years old, I was given an electric motor kit for Christmas. I had to wind a length of insulated copper wire on the rotor, put together the commutator, and install a small U magnet. I enjoyed the construction experience and with some parental assistance figured out how it worked. Ever since then, I have been curious about these simple artifacts of technology, and this article discusses some of them that I have met in my scientific travels. The small electric motor is a simple piece of technology that is based on mechanics, electricity, and magnetism and is a good mechanism for drawing students into physics.
