    You can use chemical batteries to create electric current without magnets.

    You can also create weak permanent magnets by just hitting iron with a hammer.

      Looked it up, this looks the easiest to tech up. You still have to heat it up to a dark red color, align it north to south and then hammer. It uses the earth’s magnetic field to magnetise.

      Then tech up to stronger steel magnets.
