Comment un simple aimant crée de l'électricité ? (L'induction magnétique). Expérience scientifique.

Can we generate electricity without a battery, simply with a magnet and a copper coil? Yes! It's the principle of electromagnetic induction. In this comprehensive video, I describe the equipment, demonstrate the experiments live, and explain how this phenomenon powers the alternators in our bicycles and power plants! More information can be found in the video on the bicycle alternator and the video on energy production. This video covers the essential basics of the physics and chemistry curriculum (middle/high school). A more complete video on electromagnetism will be released later. This video covers: Description of the coil and its connection to a voltmeter. The back-and-forth motion of a bar magnet (amplitude and direction of movement). Reversal of the poles. Effect of speed. The principle of the alternator is briefly demonstrated. A much longer video will explain these phenomena in detail. For now, you can check out the video on electricity production where I show how to generate electricity with an alternator and a turbine. There's also a video about the bicycle dynamo and how it works, and many other videos on electricity and other scientific topics on this channel, "LE LABO SCIENCES" (The Science Lab). Let me know in the comments what you thought of these experiments! #Physics #Science #experiment #Induction #magnetism #electromagnetism #education #experiment #college #physic #educational #highschool #learnonyoutube #2AC #magnet
