Eddy Current - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
The exhibition items demonstrate the principle of electromagnetic damping by observing the different movements of conductors with different resistances in a magnetic field. The exhibition items demonstrate the phenomenon of magnetic damping caused by the movement of a conductor in a magnetic field. The audience places any disc from the top and drops it, only to find that the disc is not freely falling, but slowly moving downwards. When participating, the audience places different disks from the top and drops them, and will find that different metal disks fall at different speeds, thus understanding the magnetic damping of the conductor. When a metal disk moves in a magnetic field, eddy currents are generated, and the better electrified the metal disk, the greater the eddy currents generated, the stronger the damping, and the slower the descent speed. Exhibition items use permanent magnets as tracks, and different disks slide at different speeds from the middle.
