    Induction!

    Did you ever do the experiment where if you coil a wire, and then hook it up to a battery, it becomes magnetic?

    Well it works in reverse, too. If you move a magnet near a coil, it generates power! Specifically, its the motion of the magnet that makes power, so the magnets are mounted to the spinny spinny bit and the coils are in the base hooked up to the grid.

    (this is an oversimplification)

    In slightly more detail, motors work on the same principle, since they’re just magnets and coiled wires. Apply power to the leads to spin the motor, but also, you can spin the motor by hand like a crank to generate power at the leads.

    This is also how wireless charging works. Power goes into a wired coil that makes a magnet that makes power in another wired coil inside your phone,

    This was me. Not all of it was yee yee jesus. A lot of ot can be more relatable, like overcoming adversity not necessarily with the help of a higher power, or expressing frustration at injustice. Even a decent amount of the god-fearing songs were subtle enough to be mistaken for love songs. I’m not religious, but it was nice to have the option in my household.
