Got galvanic power source? Wrap the coil around a piece of iron/cobalt/nickel and blast power at that stuff. After a while, you'll get a magnet.

    That would take a lot of time

    Sure would. But once you can have that, you can build better energy generators and more powerful machines.

    Now, how does one make a wire?

    You can cast a basic draw plate with regular forms. It won't be good, and the wires made with it will be terrible by any modern standards, they will also break more easily, but it will get the job done.

    Then you heat up fine copper or silver (both can be obtained since ancient times), roll it to a thin wire-like structure, heat it up again and put it through the draw plate. Yay, you got a wire!

    Correct me if I'm wrong, but wouldn't that be extremely tedious while more modern extrusion process would not possible without precision machining?

    True

    But no one said it would be easy. We have all this machinery refined over the centuries for a reason, but doing rough models first would help jumpstart entire industries that would help recreate the rest much faster and without jumping through the hoops.
