        No, wind is spinning magnets. Everything except photovoltaics and fuel cells is spinning magnets. (Everything with boiling water is also spinning magnets)

          There’s peltier devices, too, which use heat traveling via different metals and maybe some sort of sorcery to generate a voltage.

          Also teslacoils use a different mechanism (friction I believe), though that’s a static voltage.

          In theory, you could translate a magnet through a coil instead of just rotating it to produce a current. Lol spinning a ring magnet through a rounded coil could be a different way of using spinning magnets (assuming it isn’t already done).

            Well… if a wire moves in a magnetic field, a current is induced. If a current runs through a wire, it generates an electromagnetic field.

            So in this case: spinning wire = spinning magnet

          We’re kinda just using magnets to push around other magnets remotely.

          And then there’s other stuff attached to those magnets.
