Electron flow is created by moving a coil in a magnetic field, afaik, doesn't say which way you have to move it for the flow, BUT, polarity may matter since you use the right hand rule of flow. Magnets make useable power at low speeds, alternators take some speed to self excite. Not as valid if you externally excite the field but they do trade efficiency for current flow.
