Music Tesla

Electromagnetism

★Exhibit Content: Tesla High-Voltage Discharge ★Interaction: Electromechanical Interaction ★Operation: 1. Staff turns on the power; 2. Visitors stand in the safe area, observe the discharge phenomenon of the musical Tesla coil, and listen to the beautiful music produced by high-voltage current breaking through the air. ★Exhibit Description: The exhibit consists of a platform, primary coil assembly, secondary coil assembly, grading ring, protective cover, etc. The device can produce rhythmic music. Interestingly, these sounds are not played by audio equipment, but are generated by high-voltage current breaking through the air. These sounds change continuously as the LC resonant circuit inside the device adjusts the pulse frequency, thus forming undulating beautiful music. During the demonstration, the high-voltage current generated by the device is like a lightning bolt in the dark, piercing through the air and jumping onto the surrounding lights. The lightning will excite and light up the tubes, like a conductor of a symphony orchestra waving a baton. The music follows the flickering and intensity of the lights, rising and falling, performing dreamlike songs of science. ★Scientific Principle: Tesla discharge is a type of high-voltage discharge and an attempt by humans to create 'artificial lightning'. Its working principle is to first use a transformer to step up the voltage, then charge the primary circuit capacitor. When the charge reaches the discharge threshold, the spark gap discharges and conducts, causing electromagnetic oscillation in the primary circuit, which provides sufficient excitation power to the secondary coil. Since the natural frequencies of the primary and secondary coils are set equal, electromagnetic resonance can occur, and the secondary coil can accumulate extremely high voltage. When the voltage can break through the air, we see artificial lightning.
