How does a Tesla coil work? Take a wild journey through time from the invention of the electromagnet, through a shocked Irish priest and the discovery of radio waves to Tesla's dramatic displays! Check it out! Timeline: 1800 Volta invents the battery: https://youtu.be/f6wJfx0VYRY 1820 Oersted discovers that current creates a magnetic force: https://youtu.be/2yawV5ekyN0 1826: Sturgeon creates the electromagnet: https://youtu.be/DbGrHMTlyjM 1831: Faraday discovers induction: https://youtu.be/MpjoGC-Prks 1836: Reverend Callan shocks himself with coils 1853 Fizau added a Leyden jar to the circuit 1866: Hertz used induction coils to create Radio waves: https://youtu.be/E46ZU2rsupA 1889: Tesla heard of Hertz's waves 1891: Tesla patented his Tesla coil Acknowledgments: The lovely modern tesla coil movie comes with permission from Greg at http://hotstreamer.deanostoybox.com/greg/frames.htm He has some great advice if you are crazy enough to try to make some of these machines yourself.
