Exclamation Speaker Wire vs. Enameled Wire

I have a science project to build a hydro generator, I went to home depot to get wiring for the coils and he gave me some copper wire, the copper wire was twisted and stuff and it looked fine, so I bring it home then i realized the wire had to be enameled, and I doubt he gave me enameled wiring and by the looks of it it doesn't look enameled. (Then again it might be) So I was looking through my house and found some speaker wire, covered in plastic and it had 2 wires in it... If i strip both the pieces apart can those be used as wires to be coiled for the electricity generation?

Short answer no.
You need enamelled wire which you won't find at Home Depot.
Google it.
If you live in a large city, maybe you can find a guy who rewinds electric motors, he might sell you a little.
Or get an old but still good transformer (it won't do if burnt) and carefully disassemble it.

Oh okay I see, are there any other appliances that may have it in them?

With the speaker wire, the fill factor of your coils will be very low, because the thick insulation takes up space that is not available for windings, leading to poor performance as a magnet or generator coil.

Better get some (enameled) magnet wire. Or sacrifice an old transformer and unwind it. It's quite easy after removing the laminations...

Regards,
Andreas

This thread makes me remember when sometimes a guy say that an antenna can't be done using isolated wire.

Definitively YES, but perhaps the gross insulation robs window space.

I'm fine with space being lost but would it work? I am barely powering a small lightbulb. As long as it works (Faint glow) It should be fine... So can I coil it?

Surely. Do it and check it!

Wait so the speaker wire comes looking like this

Click the image to open in full size.

Do I separate both cables then coil it?

Do you know how many current will flow by this conductor? Be sure that current density (Ampers div mm squeared of copper area) isn't less than 4 A/mm2. If this isn't the case, the wire will become overheated.

Yes, if you want to try, separate it then coil it.

Another question comes to mind: Do you have to build everything from scratch? A small DC motor with a permanent magnet stator (as used in many toys, car stuff like power windows, wiper etc) would work as a generator if your model power plant makes it mechanically turn.
