After receiving the goods, peel off the protective film on the carrier plate, otherwise it will not be easy to peel off after a long time. An experimental teaching tool that realizes rolling back and forth by electromagnetically changing the direction of movement of the steel ball and rolling back and forth. Find the built-in steel balls, place them on the rail and move the steel balls by hand to check the concentricity of the rail and prevent beads from falling out. Plug in the plug. If the indicator lights of the coils at both ends turn red, the operation is normal. Let the steel ball slide into the coil at one end. The blue light flashes, and the steel ball automatically moves to the other end, etc. If you find any problems with our products, please contact us by email to solve the problem. › See more product details; Product description Principle description: When the steel ball rolls to the outside of the drive coil, the infrared tube (the black and white tube on the drive board) detects the arrival of the steel ball. The drive coil is activated and creates a strong magnetic field that instantly pulls the steel ball to the center line of the coil (the middle part of the activated coil has the greatest magnetic field strength). Due to the attraction, the steel ball leaves the infrared tube. The detection coil is switched off and loses its magnetic field. Due to the inertia, the steel ball rolls to the other side. The coil starts again and again from the front. The steel ball never stops. Purpose: Electromagnetic experiment equipment Input Voltage: 24V 4A Configuration: low voltage power supply x1. Applicable to: science and technology exhibitions, teaching, experiment groups, home textiles Dimensions: 430 mm long, 60 mm wide, 75 mm high. - Easy to carry, suitable for photography, teaching, learning, demonstration, etc. It is the perfect tool for chemistry lessons. - Simple structure, easy to use, easy to disassemble, easy and convenient to use. - Adjustable design to meet your needs easily, you can adjust the height according to your needs. - The product has good stability and can effectively prevent the funnel from falling off. - Made of high quality iron material, sturdy and durable. The coating has excellent optical quality and adhesion. Function: Good teaching tool It has a good experimental display effect.; Product description Principle description: When the steel ball rolls to the outside of the drive coil, the infrared tube (the black and white tube on the drive board) detects the arrival of the steel ball.
