Building a motor lab
Students in Teacher Glenn’s EP M5 Physics class conducted a hands-on motor building lab using a guided worksheet to explore how electric motors work. Using materials such as batteries, magnets, enamel wire, and paper clips, students constructed a simple electric motor and observed how electric current and magnetic fields interact to create motion. They applied the left-hand rule to predict the direction of force on the armature and investigated how the motor continues spinning due to inertia. Through testing and analysis, students identified the key parts of the motor, explained how the current and magnetic field produce rotation, and explored ways to change the motor’s direction and increase its speed. This practical activity helped students connect electromagnetic theory to real-world applications through experimentation and problem solving.
