Multifunctional BT music Tesla coil has the function of wireless transmission, produces touchable electric arc, lights up lights, and plays music with high sound quality. With the Tesla coil, you can create dazzling artificial arcs that can be used not only in games or art but also for various scientific experiments such as wireless power transmission, wireless light illumination, insulator voltage testing, sewage treating process, etc. And teachers can use it to demonstrate the principle of voltage boosting to students, high-frequency skin effect, etc. It is a perfect teaching tool to arouse students' interest in science, also can be a fine gift. Features: Beautiful Appearance:It is compact in size, light and portable, beautiful and stylish, with fine durability by adopting a strict production process. The electric arc effect of this Tesla coil is very dazzling and interesting, and it is also a beautiful decoration for your home at night. Touchable Artificial Arcs:It produces a palpable arc that, when touched by the hand, provides a sensation similar to a soothing hand massage at a SPA. Two rotary knobs design for you to adjust the the size of the arc and the working frequency. Wireless Transmission:The Tesla coil can generate a high frequency and high-pressure electromagnetic field so that the lights containing conductive gases can be illuminated by the electromagnetic field. Includes fluorescent light, LED light, neon light, and some rare gas-glass tubes. Ignition Mode:With ignition mode, the arc is essentially a high-temperature plasma that can ignite flammable materials when the device releases arcs at a high frequency. BT & AUX Music Input Modes:Features a dual music playback modes design, users can enjoy their favorite songs. AUX audio cable mode through the audio cable connected to the device to plays squarewave music, also can freely adjust the length of the electric arc and the frequency. BT music mode plays squarewave music by connecting the device with BT through cell phone, the electric arc flashes with the rhythm of the music and makes sound by vibrating the air, the discharge frequency is higher and the arc effect is dazzling and stunning. Experimentation Teaching Aid:It is a perfect teaching tool to spark students' interest of science, suitable for various scientific experiments such as wireless power transmission, wireless light illumination, insulator voltage testing, sewage treating process, etc. And teachers can use it to demonstrate the principle of voltage boosting to students, high-frequency skin effect, etc. Specifications: Name: Music Tesla Coil Material: acrylic + printed circuit board Music transmission: BT+AUX input Input voltage: 48V Arc length: 0-80mm Arc frequency: 5-50Hz Item size: 39 * 90 * 90mm / 1.54 * 3.54 * 3.54in Package size: 200 * 110 * 140mm / 7.87 * 4.33 * 5.51in Package weight: 514g / 1.13lb Packing List: 1 * Music Tesla Coil 1 * Power Source 1 * Tweezer 2 * LED Light Beads
