Exploring Magnetism and Electric Currents: DC Motor Lab Activities

In this engaging autumn quarter lab, students will delve into the principles of magnetism, electric currents, and their applications in motors. Activities include studying the right-hand rule, analyzing electromagnetic concepts, and constructing a simple DC motor. Students will experiment with stepper motors, exploring optimal switching sequences for rotation. Using oscilloscopes, they will assess the signals controlling servo motors. Come ready to build, analyze, and uncover the fascinating world of electromagnetism through hands-on learning.
