The general concepts of electricity are actually pretty simple to grasp.
- You've got a magnet
- You've got copper coiled around the magnet, (or iron, or some other Ferromagnetic material)
- The copper sits still while you rotate the magnet - moving the electrons in the copper coil into a certain direction, which is electricity.
Thus ends the "electricity for dummies" class
Being sent back in time, I could know those concepts, but I wouldn't know how to get or create the magnet. I've tried doing research into "how to create a magnet", but nearly everything I find uses today's technology, which seems to use other magnets to make it magnetic.
Given that one has traveled back in time, and doesn't really know where they are located or where they need to go to find a magnet, would it be possible for them to create one for the purpose of re-inventing electricity? If so, how?
(The locals have access to iron, copper, and possibly other raw materials you may need, but they don't have any already-magnetized iron)
