Description:
Specifications:
Item Name:Columbus Egg Rotating Magnetic Field Model
Type:Aluminum Ball Version(Type A) / Aluminum Egg Version(Type B)
Voltage:220V
Current:200mA
Power:24W
Dimensions:130*125MM
Weight:1.687KG
Design Principle:
For the Columbus Egg to operate, it must have two-phase AC power with a 90° phase difference. Therefore, we employed a single-phase induction motor approach, employing capacitor phase separation, where the capacitor voltage lags the current by 90°. This solved the Columbus Egg"s power supply problem.
The Columbus Egg is an egg-shaped copper block that spins about its long axis in a rotating magnetic field, eventually standing upright due to the gyroscopic effect.
Features:
- Transparent Acrylic Design: Featuring a clean and enduring acrylic structure for a clear view of the intricate rotating magnetic field mechanics and Tesla demonstration.
- High-quality Copper Coiling: Premium copper wires ensure efficient energy transfer, stable operation, and consistent performance.
- 35mm Solid Brass Sphere: Precision-made 35mm brass sphere acts as the central component of the rotating field demonstration.
- Custom Soft Magnetic Core: Optimized silicon steel core provides enhanced electromagnetic efficiency and low energy loss.
- 3D Printed Coil Frame: Advanced 3D printed elements ensure high structural integrity and aesthetic refinement.
Note:
- Do not modify the power supply voltage or power without authorization.
- Do not connect the power cord without authorization.
- This product is made of acrylic; do not expose it to direct sunlight.
- Acrylic is fragile in winter or when temperatures are low; please handle with care.
- Do not touch the rotating motor with your hands; you will be responsible for any consequences.
