The distance between observer and wind farm usually forms the strongest influence on the visual impact perception. Although a single wire carrying current produces a magnetic field, coiled wire wrapped around an iron core produces a stronger one. They both work on the scientific principle of electromagnetic induction, discovered by scientist Michael Faraday in 1831, which says that a moving electric current will create a magnetic field, and vice versa.
