they’d probably have non-shitty copper by then, but magnets? thems witchcraft
And don’t forget that you need to demonstrate that it’s producing a current. Just get a light bulb, right??
probably go with a hand-crank zapper or something. it’s tricky to do much without resistors and capacitors.
If you can make a generator you can make a motor, just connect them together and have one move when you spin the other
Probably easier to use a lemon and copper plates. Not sure what you’d connect to it though
You can literally mine lodestone and copper. Ancient people have mined those two things since antiquity. Where do you think it comes from now? Fairies?
Bring a live translation device, and program it with whatever the expected language is. That alone would be magic to them. And you don;t need to go to a copper mine, there were markets for processed copper. Pulling it into wire is just a case of roughly forming it into a cylinder, then pulling that cylinder through successively smaller holes. A local smith could help you with that.
You literally could just go dig some yourself while they’re away and procure it that way.
