Product overview This demonstrator illustrates the principle of a rotating magnetic field and the basic working principle of a motor. The device is composed of a bracket, a strong rotating magnet housed in an aluminum frame, and a thimble that allows the aluminum frame to be turned manually. When the aluminum frame and magnet rotate relative to a nearby conductor, the changing magnetic field induces a current in the conductor, producing an observable ampere force. Key benefits Makes abstract electromagnetic concepts visible and tangible, helping learners understand induced current and motor action faster and more reliably. Simple, handson operation supports inquirybased learning for classrooms, labs, and home STEM activities. Durable materials and straightforward design enable repeated demonstrations and experiments without complex setup. Main features Construction: bracket, aluminum frame, rotating strong magnet, and a manual thimble for rotation. Function: demonstrates how a rotating magnetic field relative to a conductor induces current and produces ampere force. Materials: aluminum frame for rigidity and magnetic compatibility; strong magnet for clear experimental effects. Operation: manual rotation of the thimble turns the aluminum frame and magnet so the magnetic field rotates relative to a conductor. How it helps Visualizes cause and effect: students can see how motion of the magnetic field produces measurable electrical and mechanical results. Supports curriculum goals: suitable for demonstrations of electromagnetic induction, forces on currentcarrying conductors, and basic motor principles. Improves learning efficiency by providing a direct, repeatable experiment that complements theoretical instruction. Typical use scenarios Classroom demonstration: set the demonstrator next to a conductor loop during a lecture or lab to show induced current and resulting forces in real time. Physics lab experiment: integrate into handson exercises where students measure induced current or observe directional forces as the magnet rotates. STEM enrichment and projects: use in science fairs or student projects to demonstrate motor principles and electromagnetic induction. Simple setup and operation Mount the device on a stable surface using the bracket. Place a conductor or conductor loop in proximity to the rotating magnet assembly. Turn the thimble to rotate the aluminum frame and magnet. Observe the induced current in the conductor and the resulting ampere force. Suitable for Educational settings, including school and introductory college physics. Home STEM learning and student projects. Demonstrations and handson workshops where basic electromagnetic principles need to be shown clearly. This demonstrator provides a clear, mechanical example of rotating magnetic fields and their interaction with conductors, making it a practical tool for teaching and learning fundamental motor and electromagnetic concepts.
