When you first look at this motor you think it is very simple. Sometimes things are not always as they seem. This motor can be found on several electronic websites and it appears it is used by several schools as science experiments. Although it is small and looks easy to build, you have to be sure you attach the wires solidly or the battery will not make the armature turn. It is good if you have small or slender fingers to build this motor. Once you get all of the wires attached and the battery is installed this motor will run like a top.
