Gamvdout Coil DIY Musical, Coil Kit, 400W Experiment Model with The Function Of Playing Music, Lightning Science Teaching Experiment Model, Small, Beautiful

-- High-frequency alternating current: Using coils to generate high-voltage, low-current high-frequency alternating current will produce magical effects and stimulate 's interest in science. This is a very interesting teaching material. -- Audio input: This ring has the function of playing music, and can support audio sockets, mobile phones, computers, etc., and can play any form of music. The ring can transmit current in the air to light up neon lights, energy-saving lamps, and strobe lights. -- Sturdy and durable: This coil is equipped with a dedicated heat sink, cooling fan, and equipped with a reasonable circuit design. The heat dissipation effect is good and can be guaranteed to for hours. No manual is required. Plug and play! No grounding required -- Easy to use: Small and beautiful, easy to display. The large air volume fan is silent, quiet and noiseless, ensuring long-term use, and can to create high-voltage lightning, conduct various scientific experiments such as wireless power transmission, wireless lighting and insulator withstand voltage testing. -- Safety teaching kit: This is a smart device for wireless transmission experiments. The discharge spark at the top of the coil is a high-temperature plasma, which will not cause electric shock, but may ignite objects. Keep away from flammable objects and pay attention to fire and scald prevention.
