Students will build a simple DC motor out of metal coat hangers, a 24-guage wire armature and field magnet, 14-guage wire brushes, and build the motor so that it rotates when connected to a 10-volt DC power supply. Students will understand the principles of operation of the DC motor, to include: induction of an electromagnetic field Via current flowing through a conductor (electromagnetism), and become familiar with the notion that Forcetotal of the motor is proportional to charge, proportional to speed, proportional to the induced magnetic field.
