Whats the difference between enamelled copper wire and bare copper wire in terms of conductivity? I need to make a coil and want to know which one is better enamelled copper wire or bare copper wire to make and electromagnet. I think you've misunderstood: conductivity is a property of the material, and as copper is the conductor in both, there is no difference in conductivity. What you may be getting at is the resistance of the wire. For a given outside diameter, enamelled copper wire will have a higher resistance per unit length, because the cross-sectional area of copper is less (it's the diameter of the copper core that matters, and that is of course less than the outside diameter by twice the thickness of enamel). Of course, if you are winding a coil of touching turns, bare copper is a non-starter because the turns would short-circuit together. If you use bare copper wire the current will just flow right across adjacent coils without going through the loops.Kind of like short-circuiting. To make an electromagnet you should always use enamelled copper wire.paper covered wire for lifting motor suppliers There is no difference in the conductivity of the wire. The enamel is just away of insulating the wire like the plastic covering on the power cable to your computer. None. The conductivity and resistivity as long as the CSA is the same will be the same between the two. The enamel is just more durable to the elements.SZ CABLE mainly supply: 1-Enameled Wire( CCA wire, Al. wire, Copper wire) 2-Electric wire( CCA wire, Al. wire, Copper wire) 3-Electric cable( CCA wire, Al. wire, Copper wire) h class enamelled copper wire for Transformer 4-Bare/tinned conductor wire( CCA wire, Al.-alloy wire, Copper wire) 5-Enameling machine(size from 0.02-8.00mm wire) Advantages: as the most traditional type of enameled wire, the application field is wide, soldering convenient, performance stable.

magnet wire is coated with some red fancy insulation. Is that just an enamel? If so, enamel coated copper wire & magnet wire would be the same thing. I want to build a loudspeaker. This what I need? Are the coils used in loudspeakers the same ones used in inductor coils? One interesting question, price of enameled copper wire for electric iron When Faraday was experimenting with the effects of magnetism on electricity, how in the hell did he figure out the magnetic field increased with the number of turns of copper in his coils! I'm only assuming Faraday didn't have insulated copper wires. "enamel coated copper wire & magnet wire would be the same thing." - They are glass-fiber covered aluminum wire for Electrical Instrument "This what I need?" - Yes "Are the coils used in loudspeakers the same ones used in inductor coils?" - Same principle, different design. The coil in a speaker is an air-wound coil designed to maximise the amount of wire that's sitting in the magnetic field. The ones in induction coils are usually designed to maximise the inductance in a small a space as possible, so they are wound on ferrite or iron cores. I think Faraday's thought process probably went something like "I wonder what will happen if I put a lot of turns in the coil. If I use uninsulated wire it will short out, so I'd better insulate it." buy magnet wire south africa They didn't make him a Fellow of the Royal Society for nothing. He used cotton insulation. Some of his equipment still exists, and still works.

The resistance of copper wire may be important in situations where an exact voltage must be supplied to a load. Knowing the resistance of the wire allows you calculate the voltage drop across the wire. Wire Resistance Formula The resistance of a copper wire is equal to Rho x (length / wire cross sectional area). For copper, Rho = 10.35 ohms-circular mils/foot (cmil/ft.) at 75 degrees Fahrenheit. Conductor resistance increases as temperature increases, and lowers as temperature decreases. enameled wire diameter Sample Calculation For 2,500 feet of 14 gauge THHN wire, we can calculate the resistance of the wire as follows: The cross sectional area of 14 gauge wire is 4,107 circular mils. Applying the formula, we have 10.35 ohms-cmil/ft x (2,500 feet / 4,107 circular mils) = 6.3 ohms across 2,500 feet of 14 gauge wire at 75 degrees Fahrenheit. Lead after evaporation zone into the curing zone, the first occurring in a curing zone is paint chemical response, crosslinking namely paint group. Such as polyester resin paint is linear structure via cross-network structure combined into a film. Curing echo very important,0.87mm magnet copper wireit is directly related to the number of wire function. The curable enough influence enameled flexibility, solvent resistance, scratch, softening breakdown. Although sometimes when the function is good, but the film invariance poor, after a period of storage, (wire) function data loss, and even failure. Suppose excessive curing, the film becomes brittle, flexibility, thermal shock decline. Most wire can determine the color of the film via the degree of cure, but because enameled via multiple baking, only the appearance of discrimination is not detailed. When the internal curing is not enough, magnet wire for transformeran external curing is very insufficient, enameled color is very good, but the release of poor thermal aging implemented, can the film sleeve or large peeling. On the contrary, internal curing well, but the lack of an external curing, wire color is also good, but poor scratch resistance.
