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?
