Magical coil producing high temperature and high voltage plasma. coils are used to produce ultra-high voltage, low current, high frequency AC power. The coil can ignite, wirelessly transmit electricity, illuminate fluorescent lamps, and produce impressive electrical arcs. A wide range of fun and engaging scientific experiments can be conducted with a coil. The device consists of two (sometimes three) coupled resonant circuits. coils are utilized in various innovative experiments such as electrical lighting, fluorescence, X-rays, high-frequency AC phenomena, electrotherapy, and radio energy transmission and reception. This product is a newly developed design. The primary coil is integrated into the PCB, eliminating the need for external winding, making it convenient to assemble, efficient, and aesthetically pleasing. The coil is designed with safety in mind and is suitable for student experiments, graduation projects, and eonal use.
