Tesla’s multifunctional flat BT coil enables wireless conduction, produces a perceptible electric arc, lights up the lamp and plays songs with high sound quality. Using the Tesla coil specifications, dazzling artificial lightning and it can only be released in games or art can, but also in various scientific experiments, including how to wireless power transmission, wireless technology, testing the power of insulators, sewage treatment, adding the use do demonstrate the principle of increasing it acid for acid, high frequency skin effect etc. It is an excellent do teaching tool to be a school student, maybe also a good gift. Perfect gift for newborn parents, newborn mother, newborn father, baby shower, birthday, Christmas, festival and so on. Gold-plated coil design, with a clear and complete coil in turn, how to make a substitution of the tesla coil design, beautiful and stylish, as evidenced. The performance-resistant design will not be interfered with by high-frequency electromagnetic signals, so you can be able to use it. The Tesla coil can produce an electromagnetic field with high frequency and high pressure, so that the wire light conductive gases can be illuminated by the electromagnetic field. The arc effect of this tesla coil is very cool and modern, as well as a beautiful decoration of the house at night. It is a perfect do tool to obtain science auxiliary support, operation do various science experiments, including how wireless power transmission, wireless lighting, insulator gain testing, sewage treatment, to enable do demonstrate the introduction of the principles of efficiency enhancement, high-quality skin effect, etc. .
