About This

• 2. Scientific principles, fun acceleration: Based on the principle of magnetic field and current force, the coil and magnet work together to easily realize the accelerated rotation of the iron ball, which can intuitively show the charm of electromagnetism and is an ideal tool for popular science education and fun experiments.
• 1. Innovative materials, stable and durable: 3D printed PLA material combined with wooden shell, with both modern technology and natural texture, the exquisite size of 16cm×16cm×7cm not only ensures the stability of the structure, but also is convenient for placement and storage. The finished product is ready for use when it is delivered, without complicated assembly.
• 4. Safe use and standardized operation: DC12V - 24V DC power supply is required, the rated output current of 12V power supply is not less than 1A, and the interface is 5.5-2.1mm (positive inside and negative outside). It is strictly forbidden to connect in reverse to avoid circuit burning; no more than 3 iron balls can be placed at a time, and 1 is recommended for stable operation. For detailed operation methods, please refer to the product video.
• 3. Precise control, circular experience: With a carefully designed mechanical structure and control system, the bracket, guide rail and transmission device support and guide the iron ball. By adjusting the current intensity and direction, the iron ball can easily achieve stable circular motion, bringing a highly ornamental visual effect.
• 5. Diverse scenarios, fun and educational: suitable for science enthusiasts to explore the mysteries of electromagnetics, demonstrate physical principles in school classrooms, or use as creative ornaments to add a technological, stimulate curiosity with interesting interactions, and feel the charm of science in practice.
