The Barlow Wheel Apparatus is a classic physics demonstration used to illustrate the principles of electromagnetism, specifically the Lorentz force, showing how electric current interacting with a magnetic field creates mechanical motion, essentially demonstrating the basic principle of an electric motor. Its primary uses are in educational settings (physics labs) to teach concepts like electric-to-mechanical energy conversion, the interaction of current and magnetism, and demonstrating the force on a current-carrying conductor in a magnetic field (Fleming’s Left-Hand Rule).
