21 Sep Science Tuition Presents Michael Faraday
Hi and welcome back to your Science Tuition. As you know, lately we have been discussing various chemists, hope you have been gaining knowledge through our classes and sharing them as well.
So proceeding with our topic, today we are about to investigate our famous chemist Michael Faraday.
Michael was born on 22nd September 1791; he is a British physicist and chemist. He was known as one of the most prolific scientists of the 19th century. His contribution to the chemistry world began while he was working as an assistant to Davy. His primary involvement was in the study of chlorine. While he was conducting experiments on the diffusion of gases, he succeeded in liquefying several gases. One of his most significant works is the invention of the earliest form of Bunsen burner. He also discovered two new components in chlorine and carbon, while one of them is used in smoke grenades, the other one is employed in the arena of dry cleaning, and spot removing.
Now take a look at some other unknown facts about him that you never knew before.
Faraday never had a formal scientific education. He earned a rudimentary education in reading, writing, and math. At the age of 14, he was apprenticed to a London bookbinder for the following seven years, in his free time Faraday read scientific books.
Faraday was highly influenced by Sir Humphry Davy, who was a charismatic chemist. One day a customer at the bookbindery gave Faraday tickets to see Davy’s upcoming lectures and Faraday made a compilation of his notes from the lectures and sent them to Davy requesting him to be his assistant. Davy secured him a job at the Royal Institution where Davy was the head of the chemistry lab.
In 1822, Faraday built a device using a magnet, liquid mercury and a current carrying wire that turned electrical energy into mechanical energy. This is simply the first electric motor. A decade after that Faraday discovered that the movement of a wire through a stationary magnetic field can induce an electrical current in the wire – the principle of electromagnetic induction. He built a machine in which a copper disc rotated between the two poles of a horseshoe magnet, producing its own power. It was the first electric generator.
Apart from this Faraday also showed the pull of Magnetic Force.
To honor his contribution towards Science he was gifted a comfortable home to live there with his family.
Faraday was also featured in the United Kingdom’s E20 currency note from June 1991 to February 2001.
