Way before his mutant counterpart the first master of Magnetism was working his way up from humble beginnings to become one of the grandmasters of the study of electromagnetism and maybe one of the greatest Experimental scientists ever his name was Michael Faraday Faraday was born on September 22nd 1791 in a Little Village in England called, Newington But his father was a blacksmith, and when Michael was old enough to become an apprentice He started to learn the bookbinding trade That was possibly one of the best things that could have happened at least for the rest of humanity Because it gave him access to a lot of books He was fascinated by the sciences And he started attending lectures by some of the best Scientists of the day one of those scientists was chemist humphry Davy who’s famous for being the first to isolate? elements like potassium and sodium in 1812 Faraday, sent a 300-Page collection of his notes on Davey’s lectures to the scientist as a sort of resume apparently Davy was impressed so he hired Faraday as the secretary and got him a job as a chemical assistant at the Royal Society [a] Society where scientists could do research and share their ideas That was extremely unusual for the time the sons of blacksmiths don’t often get to rub shoulders with science E-types at the Royal society [but] it kick-started Faraday’s career as an experimenter with access to equipment and resources faraday conducted experiments in chemistry and made enormous contributions to the study of electromagnetism one of the four fundamental forces of Nature in chemistry Faraday discovered and quantified What are known as Faraday’s laws of electrolysis? Which use math to connect the current flowing through a circuit to the mass of the chemical substance moving through the battery he also discovered an isolated lots of different chemical compounds most famously benzene a compound that has six carbons arranged in a ring and is now a Major component of Gasoline But even though he was an accomplished chemist his studies of electricity and Magnetism are what really changed the way [we] think about the universe If you’ve ever taken a physics class you’ve probably learned about an idea that’s simply known as Faraday’s law And there’s a reason why practically every physics class learns about it if you want to understand electricity and magnetism You need to know Faraday’s law the law describes the concept of electromagnetic induction where you can generate [a] current and a loop of wire by changing the magnetic field around the loop and faraday figured that out just By experimenting with a magnet and a loop of wire [the] electromagnetic induction is one of the main ways that Electricity Magnetism are connected and the idea led the development [of] electric generators and motors as well as a lot of other technology That’s used in circuits And the power grid so his ideas are basically the foundation of the technology that we use today No Big deal keep in mind that faraday did all [of] this just by trying stuff out in his lab often with rudimentary Experimental tools that he built himself there’s plenty of other stuff named after Faraday [too] because well He did a lot of things there’s the faraday [disk] a simple type of electric generator where you generate electricity by rotating a metal disc through a magnetic field might have also heard of the Faraday cage Which is basically a shield against outside electromagnetic field through his experiments including one where he lined [an] entire room with metal foil Faraday realized that if you have a conductive shell it’ll distribute electric charges in a way that keeps the electromagnetic Fields outside the shell from affecting the Inside of the [shell] these days we use faraday cages to shield all kinds of sensitive electronics from outside interference [we] also use the Farad [a] unit of measurement that tracks capacitance or how much electric charge can be stored in a system Faraday continued experimenting into the 1840s until his health started deteriorating He eventually died in 1867 at the age of 75 in a lot of ways his life and legacy Embodied the [spirit] of scientific exploration a keen mind willing to risk trying new things to see [what] we can learn [about] the universe Thanks for watching this episode of scishow brought to you by our patrons on patreon if you want to help support this show just go To patreon.com/scishow and don’t forget to go to youtube.com/scishow and subscribe
