Description: Everyone has heard of ring accelerator in physical experiments. This was originally used on particles. But we don't need to accelerate the particles. It is mainly used to study the effect of cyclic acceleration of products in Orbits. The product is currently available in 4-coil and 6-coil versions. The more coils, the faster the acceleration. Each coil is independently controlled by a circuit board and is not affected by each other. 12v low voltage electricity, safe and reliable, and long-term use power is also very low, the coil does not generate heat. Open track, easy to start, just drive steel ball by hands. The principle can be demonstrated intuitively and conveniently. Infrared sensor and special circuit are for long life, high accuracy, with no delay. Specification: Product name: ring accelerator * Voltage: 12V * Power: 8W * Size: 4-coil 32*8cm; 6-coil 30*8cm * Product weight: 4-coil 1925g; 6-coil 2419g * Electrical parameters: The ball is about 20-30 laps in the track per minute Package Includes: 1 x Set of Ring Accelerator Note: Read Before Purchasing: * Please use it on a stable and stable surface * Please do not use other voltage power supply, so as not to burn the product * Please keep the track free of debris and deformation, so as not to affect the stability of operation Use Method: * After connecting to power supply, its light will be on. Put and push the iron ball into the track and pass through any infrared pair tube to TRIGGERs operation.
