The copper magnet wire is a common magnet wire. Here we will explore its insulation.
Magnet wires are coated with enamel insulation instead of plastic or rubber coating. This makes the insulating layer thinner and allows a more compact winding, which makes the magnetic field in the coil denser.
Magnet wire also has a thinner wire gauge (thickness), which is a comparison between a solid wire and a conventional wire, which is larger in size and adopts a twisted wire form. Think of the thicker plastic coating as a waste of space, and the insulation of the magnet wire is very special, and ordinary copper wire cannot work properly.
If you want to use flux wiring, you probably should use it, because it may form a fixed polarity charge in the wire when making the wire. If what you do is as important as a turbine... you may not want it to reverse polarity in the middle of the cycle. Also make sure to install the magnet in the correct direction.
