Features 1、Magical Tesla coil, producing high temperature and high voltage plasma. 2、Tesla coils are used to produce ultra-high voltage but low current, high frequency AC power. 3、Tesla coil can ignite, wirelessly transmit electricity, illuminate fluorescent lamps, and has wonderful arcs. There are a lot of fun and very interesting scientific experiments can be done with Tesla coil. 4、Tesla coil consists of two (sometimes three sets) coupled resonant circuits. 5、Tesla uses these coils for innovative experiments such as electrical lighting, fluorescence spectroscopy, X-rays, high-frequency AC current phenomena, electrotherapy and radio energy transmission, and transmission and reception of radio signals. 6、This product is newly developed. The primary coil is already in the PCB board. It does not need to be wound on the outside. It is convenient for fans to install, high efficiency and beautiful. It is a new design. The Tesla coil is very safe and will not be dangerous. People can be used for student experiments, graduation design assignments, etc. Specification Item Type:Tesla Coil Printed Circuit Board Size:4 x 3.1cm / 1.57 x 1.22in Assembly Kit 23 g / 0.81 oz(approx.)
