Hey, I have a school project and I need a solenoid to induce a magnetic field.
http://www.yourpicbox.com/images/orhBIhKZq6426.jpg
I made a solenoid by winding a wire (I'm not sure what to call this wire. It's thin and brown.) to a pen case. I made 3 layers, 100-200 turns each.
When I tested it, connecting it to 6V DC, nothing happened. No magnet.
So I experimented other thing :
I connect a LED and 1.5V DC with this wire. LED didnt glow.
Then I change this wire with ordinary insulated copper wire. The LED glow brightly.
It seems that this wire doesn't conduct any current. What did I miss here?
