Purpose & Scientific Principle
aims to allow the audience to independently become curious about electromagnetism through various interesting and surprising discharge phenomena; and combines the historical classic experiments of famous scientists such as Faraday and Tesla with the device to vividly reproduce near-miss electromagnetic phenomena, allowing the audience to understand the electrical experiments such as capturing electricity and storing electricity done by scientists in history; and while watching the exhibition and teaching performances, they will be deeply impressed by electricity and feel the scientific spirit of having the courage to challenge authority.
How to Operate
1. Tesla coil music principle:
The Tesla coil is composed of an induction coil, transformer, lighter, two large capacitors and a transformer with only a few turns of the primary coil. It is developed by Nikolai. A transformer invented by Tesla that operates on the principle of resonance and has the characteristics of high-frequency and high-voltage discharge. Every time the Tesla coil discharges, it will cause the air to vibrate. When the frequency of the discharge changes, the frequency of the vibration also changes, thus producing different tones. Ordinary spark gap Tesla coils cannot do this. Solid-state Tesla coils are generally used. The Tesla coil is controlled by an arc extinguishing circuit board. Through that circuit board, the frequency of discharge can be controlled. If a music signal is input, the music will be released.
2. Tesla coil application:
Tesla coils are not only used in games or art. What is more valuable is that they are of great significance. For example, Tesla coils can be used to realize wireless transmission of electrical energy. This method has high transmission efficiency and is less ecologically destructive. However, there are still many difficulties and obstacles in practical application, and it is still impossible to apply it to actual power transmission.
Lightning is an atmospheric discharge phenomenon that releases huge energy when lightning occurs. Its voltage is as high as millions of volts and the average current is about 2×105A. It is estimated that the Earth is struck by lightning 45 times per second. The energy generated by a lightning strike is enough to drive an ordinary car about 290 to 1450 kilometers, which is equivalent to the energy generated by 30 to 144L of gasoline. However, it is quite difficult to utilize lightning. This is because lightning occurs in as short a time as tens of milliseconds and is difficult to capture. The Tesla coil is also an artificial lightning generator that can create dazzling artificial lightning, which is very beautiful. The exhibition demonstrates the magical phenomenon of "artificial lightning" and visually demonstrates to the audience the characteristics of high-voltage discharge of Tesla coils and the principle of "electrostatic shielding".
