How do spinning things like wind/water turbines or those spin to charge flash lights make electricity by just spinning?
In: Engineering
Thing thing to keep in mind is that electricity is not the electrons themselves, but their movement. One of the handy-er ways to think about electricity is to use a water analogy.
Imagine that the there’s a coil of water tubing around a turning magnet, like if you wrapped a tube around the edges of a fan.
Now imagine that magnet can grab the water molecules, with a magnetic field. When the turning magnet pulls the water “down” or “up” it pushes or pulls the water in the coil.
Eventually the tube/coil heads away from the magnet to do something useful, and because of water pressure, even once the water is away from the magnet, the water behind it keeps it moving.
It’s not a great model but it gives me a handy visual.
