Electromagnetic Relay - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

Why can a small car move upwards through electromagnetic relay? Magnetism is closely related to points. Electricity can generate magnetism, and magnetism can also generate electricity. When a coil is connected to a current, the coil generates an induced magnetic field, which attracts the movement of the car and sequentially connects the trajectory of the car through the coil. The generated magnetic field can attract the small car to relay upwards step by step. Operating instructions: 1. Press the switch to energize the coil and attract the car; 2. Press the next switch according to the trajectory of the car to attract it and form a relay; 3. Press the switch alternately to allow the ball to reach the top in the shortest possible time.
