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

    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

  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).

    And wise-ass got outwiseassed. Chapeau

    PS: you forgot to mention piezoelectricity

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

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

  Also primary battery cells.
