idk how hard youre intending to troll here but the real answer is that energy is lost to the generation of a magnetic field (and some tiny bit to the electricity flow generating heat and it compounding since heat makes the wiring more resistive) so even with no air resistance a dynamo would eventually come to a stop.
if you play with using motors as dynamos youll notice they actually generate quite a bit of friction despite the average motor having good tolerances, quality bearings, and plenty of oil. this is basically how very primitive regenerative braking works (not really how modern cars and trains do it "properly" but you still see it on very old trains and very janky DIY e-bikes)
tl;dr electricity come from magnet move, but magnet no like move
