Magnet and Coil - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Operating instructions: Press the "Start" button, turn the handwheel to adjust the angle of the coil, and observe the changes in the brightness of the light bulb. Function Overview: Exhibitions consist of magnets, coils, LED lights, a start button, and an operating handwheel. Press the button and the magnet will start rotating. Rotate the handwheel to adjust the angle of the coil, and you will find that the brightness of the bulb changes with the angle of the coil. What is the reason for this? In a closed circuit, when a conductor cuts magnetic field lines in a magnetic field, a current is generated in the conductor, which is called electromagnetic induction. The U-shaped magnet rotates, and the magnetic field lines in the magnetic field also rotate accordingly. By adjusting the angle of the coil so that the magnetic field lines form a certain angle with the coil plane, the coil cuts the magnetic field lines, generates induced current, and the light bulb lights up; When the magnetic field lines are parallel to the plane of the coil, the coil does not cut the magnetic field lines, so no induced current is generated and the light bulb goes out. Electromagnetic induction has a wide range of applications in electrical engineering, electronic technology, electrification, and automation. For example, tape recorders, car tachometers, etc. are all made using the principle of electromagnetic induction.
