by the length of its winding. Now when all these primary-circuit components are tuned to work inharmony with each other, and the circuit's resulting frequency is right for plucking the secondary in acompatible rhythmic manner, the secondary becomes at its terminal end maximally excited anddevelops huge electrical potentials, which if not put to work, boil off as a corona of bluish light or assparks and streamers that jump to nearby conductors with crackling reports.Unlike the conventional iron-core step-up transformer, whose core has the effect of dampingvibrations, the secondary of the Tesla transformer is relatively free to swing unchecked. The pulsingfrom the primary coil has the effect of pushing a child in a swing. If it's done in a rhythmic manner atjust the right moment at the end of a cycle, the swing will oscillate up to great heights. Similarly, withthe right timing, the electrical vibration of the secondary can be made to swing up to tremendousamplitudes, voltages in the millions. This is the power of resonance.Manmade earthquakeTesla was fascinated with the power of resonance and experimented with it not only electrically but onthe mechanical plane as well. In his Manhattan lab he built mechanical vibrators and tested theirpowers. One experiment got out of hand.Tesla attached a powerful little vibrator driven by compressed air to a steel pillar. Leaving it there, hewent about his business. Meanwhile, down the street, a violent quaking built up, shaking down plaster,bursting plumbing, cracking widows, and breaking heavy machinery off its anchorage. Tesla's vibratorhad found the resonant frequency of a deep sandy layer of subsoil beneath his building, setting up anearthquake.Soon Tesla's own building began to quake, and, just at the moment the police burst into the lab, Teslawas seen smashing the device with a sledgehammer, the only way he could promptly stop it. In asimilar experiment, on an evening walk through the city, Tesla attached a battery-powered vibrator,described as being the size of an alarm clock, to the steel framework of a building under constructionand, adjusting it to a suitable frequency, set the structure into resonant vibration. The structure shook,and so did the earth under his feet.Later Tesla boasted that he could shake down the Empire State Building with such a device, and, as ifthis claim were not extravagant enough, he went on to state that a large-scale resonant vibration wascapable of splitting the Earth in half. No details of Tesla's vibrators are available, but they probablyresembled one of Tesla's reciprocating engines (such as Patent No. 511,916). These exploited theelasticity of gases, just as his electrical vibrators, like the Tesla coil, exploit the elasticity of the electricmedium.A new power systemTesla invented his resonant transformer, as the Tesla coil is sometimes called, to power a new type ofHệ thống chiếu sáng tần số cao, như của mình bằng sáng chế năm 1891 vẽ cho thấy.

This type of current also renders conductive materials that are normally nonconductive,rarefied gases, for example. You might say these currents make a medium superconductive.Although super-magnetism is not in the picture because high-frequency vibrations would be severelydamped by an electromagnet's iron core, it is revealing to reflect upon the unexploitedsuperconductivity of Tesla energy these days when science is congratulating itself on new advances inthe field. Prior to recent breakthroughs, superconductivity and super magnetism were low-temperature(cryogenic) phenomena, occurring when circuits were cooled down to near absolute zero. The newsuperconductivity at less drastically reduced temperatures developed out of the cryogenic work of thelast twenty years, and this may be in debt to Tesla, who patented a similar idea way back in 1901.Tesla's patent shows that the deep cooling of conductors with agents like liquid air results in anextraordinary magnification of the oscillation in the resonating circuit. Imagine the performance of asuper cooled Tesla coil. No electrocution. Since we tend to associate high voltage with possibly fatalelectric shock it may be puzzling to learn that the output of a well-tuned Tesla coil, though in themillions of volts, is harmless. This is customarily thought to be because the amperage is low (it's not)or it's explained in terms of something called the skin effect, which means that the current travels overyou instead of through. But the real reason is a matter of human frequency response. Just as your earscannot respond to vibrations over about 30,000 cycles, or the eyes to light vibrations at or above ultraviolet, your nervous system cannot be shocked by frequencies over about 2,000 cycles.ElectrotherapyNow that you know it's harmless, would you believe these currents are even good for you? Fact is thata whole branch of medicine was founded on the healing effects of certain Tesla coil frequencies. Teslaunderstood the therapeutic value of high-frequency vibrations. He never patented in the area but didannounce his findings to the medical community, and a number of devices were patented andmarketed by others.
