You could always spin some wire and let the magnets stay still if you wanna be different.

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).

Also primary battery cells.

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

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