About This Product
Enamelled copper wire, also called magnet wire, is used to wind coils for electromagnets, solenoids, transformers and simple motors. The thin enamel insulates one turn from the next, so the turns can be wound close together, and it must be scraped off the ends before connections are made. Students wind coils on a nail or former, investigate how the number of turns and the current affect the strength of an electromagnet, and use the table of resistance for each size to estimate the resistance of a coil.
