Genecon Wire Coil Pack of 6 jacketed distillation heads this efficient device helps toThe Genecon Wire Coil Pack of 6, each containing 400 wire turns wrapped around a core. These coils are specifically designed to work with educational hand cranked generators, such as the Genecon models, for experiments and demonstrations in physics. The coil's inductance is affected by the number of turns (400), which can be manipulated in experiments to study the effects of various factors on electrical current generation. *Used with the Genecon Due
