Coil Demonstrator Rotating Magnetic Field Model with Aluminum Egg Stepless Speed Control for Physics Teaching and Science Experiments
Columbus Egg rotating magnetic field demonstrator A compact, handson model that visualizes the rotating magnetic field and gyroscopic behavior behind asynchronous motors. The aluminum egg (30 mm x 50 mm) spins along its long axis driven by magnetic eddy currents and, after reaching speed, stands upright due to the gyroscopic effect. Clear, reliable demonstrations make complex principles easy to see and explain. Key benefits Makes the principle of rotating magnetic fields and asynchronous motors tangible and memorable for students and audiences. Robust construction for repeated classroom or lab use: aluminum egg with wearresistant glossy coating and a solid wood base with stable central support. Precise, userfriendly control lets instructors demonstrate slow starts through speed upright behavior using a stepless speed control button. Clean, durable finish reduces fingerprints and daily wear while the antislip base keeps the unit stable during demonstrations. Attractive design suitable for teaching, research displays, or desktop conversation pieces. Features and what they mean for you Demonstration function: Shows magnetic eddy current drive and gyroscopic upright behavior to illustrate asynchronous motor principles in a single, selfcontained device. Egg body: 30 mm x 50 mm aluminum construction with a glossy, wearresistant coating for longlasting visual clarity. Base and support: Solid wood base with rivetfastened central support and wooden turntable for stable operation and refined presentation. Controls and indicators: Metal toggle switch, stepless speed control button for precise adjustment, and power indicator light for immediate status feedback. Hardware and access: Dovetail hinges for smooth opening and closing and durable fastening to withstand frequent use. Typical applications Classroom and lecture demonstrations: Use during physics or electrical engineering lessons to show realworld motor principles in a compact format. Laboratory and STEM workshops: Provide a reliable visual aid for experiments, lab exercises, and handson student learning. Display and outreach: Place on a museum exhibit, science fair booth, or office desk to engage visitors and spark discussion about electromagnetic and rotational dynamics. Quick specifications Function: Rotating magnetic field and gyroscopic effect demonstrator illustrating asynchronous motor behavior Egg size: 30 mm x 50 mm Egg material and finish: Aluminum body with wearresistant glossy coating Base: Solid wood with antislip and abrasionresistant properties; rivetfastened central support and wooden turntable Controls: Metal toggle switch, stepless speed control button, power indicator light Hardware: Dovetail hinges for smooth access This demonstrator combines visible operation, durable materials, and fine control to support teaching, demonstrations, and display without complex setup or maintenance.
