I need to check Tesla's patent dates, LOL
>>Matteucci's Apparatus
In his experiments in 1830 with electromagnetic induction, Michael Faraday discovered that a change in the magnetic flux produced by one coil produced an EMF in a parallel coil. In his experiments the two coils were close together and linked by a length of iron.
| The Italian experimenter, Carlo Matteucci (1811-1868), in experiments in the mid-eighteen forties, showed that the effect worked over larger distances without the presence of iron. He devised a pair of identical flat coils, with wire wound in a spiral pattern on the surface of glass disks about 30 cm in diameter. A Leiden jar was discharged through one of the coils, and an experimenter holding on to wires connected to the other coil felt a shock. The magnitude of the shock increased when the distance between the two coils decreased. Matteucci is also known for his work with the electrical conductivity of the earth in 1844. By demonstrating that the earth has an appreciable conductivity, he showed that it was possible to use the earth as a return conductor for telegraph signals, thus making it possible to use one metallic conductor instead of two. << http://physics.kenyon.edu/EarlyApparatus/Electricity/Mattenuccis_Apparatus/Mattenuccis_Apparatus.html |
