I know it’s sometimes made via kinetic energy rotating magnets but that might be to complicated an explanation. Trying to figure out an easy way to explain the generation part to some kids!
In: Technology
Copper is a dense, soft metal with a lot of tiny, energetic electrons in it. If you bundle a lot of copper together in wires and wrap them around a magnet, then spin the magnet the quick positive/negative change of the magnet makes the tiny electrons ‘jiggle’ about. They can ‘jiggle’ more easily on the surface of the copper, which is why we use copper wires, not a big solid block of copper. The jiggly electrons near the magnets pass on their energy to the electrons further away and so on, along the copper wires to something like a lightbulb. There, they make the tiny electrons in the filament of the bulb jiggle too, making them very hot. They get so hot that they ‘incandesce’ or glow brightly. The bulb filament releases clumps of electrons which are called ‘photons’ which is light.
