Brushed magnet-less motor demo

Writer: KrisKris

As a high school project we were asked to make a simple electric motor for demonstration purposes. While most classmates chose to build a motor using a magnet and a rotating armature coil, I chose to take it one step farther and eliminate the use of a permanent magnet by way of using an armature coil and a field coil with primitive copper brushes to allow the armature to rotate freely while making the the switching polarity electrical connections needed to propel the armature.
