iDili DIY Perpetual Motion Machine Model - Physics Electromagnetic Energy Conservation Teaching Demonstration

DIY Perpetual Motion Machine Model - Physics Electromagnetic Energy Conservation Teaching Demonstration Specifications: Material: 3D Printed PLA + Wooden Shell Dimensions: 17cm (L) × 8cm (W) × 13cm (H) Input Voltage: AC 100-240V Operating Voltage: DC 12V Shipping Form: Pre-assembled Finished Product (Ready to Use) Usage Guidelines: Power Requirements: Use a DC power supply above 12V, but DO NOT exceed 24V. For 12V operation: Ensure the power adapter has a minimum rated output current of 1A. Connector Specification: 5.5×2.1mm DC jack (Center-positive polarity). WARNING: Reverse polarity will damage the circuit. Operation Tips: Recommended Ball Quantity: 1 (Optimal for stable operation). Maximum Capacity: 5 balls. Exceeding this limit may cause insufficient electromagnetic thrust, preventing the balls from cycling back to the charging tray. Applications: Physics classroom demonstrations (energy conservation, electromagnetism). Creative science decor for offices or homes. STEM/STEAM educational gift for teens and adults.

• Hands-on STEM educational model for demonstrating energy conversion and conservation principles.
• Combines electromagnetic physics with dynamic mechanical design.
• Ideal for classroom teaching, science fairs, or DIY physics enthusiasts.
