Electromagnetic Stage - Music Tesla

The exhibit showcased the magical phenomenon of "artificial lightning", visually demonstrating the characteristics of Tesla coil high-voltage discharge and the principle of "electrostatic shielding" to visitors.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

This exhibit uses a music Tesla instead of the traditional Tesla device, which can produce rhythmic music sounds. Interestingly, these music sounds are not played by audio equipment, but are generated by high-voltage current penetrating the air. These sounds continuously change in pulse frequency with the adjustment of the LC resonant circuit inside the device, forming beautiful music with ups and downs. During the demonstration, the high-voltage current generated by the device was like a lightning bolt in the darkness, piercing through the air and leaping onto the iron cage on the opposite side. This lightning bolt was like a conductor of a symphony orchestra, waving his baton, and the music varied with the intensity of the electric light, performing dreamlike songs of science.
