2. Brief History of Faraday
Michael Faraday was born in south London On September 22nd 1791.
At the age of 14 he was apprenticed as a bookbinder.
He came from a middle class family and received a basic education.

3. Brief History of Faraday
He educated himself in science by reading from books and attending four of Humphry Davy’s lectures in 1812.
Served as a chemical assistant at the Royal Institution and accompanied Davy (and his wife) on an 18 month tour.

4. Some of Faraday’s accomplishments:
Faraday invented an early form of the Bunsen burner.
He was responsible for discovering the laws of electrolysis.
Contributed in coining the terms anode, cathode, electrode, and ion.

5. Main Discoveries
Electromagnetic induction -production of an electromagnetic force across a conductor when it is exposed to a varying magnetic field.
Diamagnetism-when many material exhibit a weak repulsion from a magnetic field.
Electrolysis-method of using a direct electric current to drive on otherwise non-spontaneous chemical reaction.

6. More Discoveries
Mutual induction- wrapped two insulated coils of wire around an iron ring, and found that upon passing a current through one coil a momentary current was induced in the other coil
Built two devices to produce electromagnetic rotation
Ex. Homopolar motion-caused a continuous circular motion that was engendered by the circular magnetic force around a wire that extended into a pool of mercury. Wherein was placed a magnet, the wire would then rotate around the magnet if supplied with current from a chemical battery

7. More Discoveries
placed two opposite electrodes in a solution of water containing a dissolved compound. He observed that one of the elements of the dissolved compound accumulated on one electrode, and the other element was deposited on the opposite electrode
Faraday’s demonstrations established that a changing magnetic field produces an electric field

8. Summary:
Faraday discovered that electrical forces were responsible for the joining of atoms in a compound.
Anode -The positive electrode in an electrolytic cell
Cathode -The negative electrode at which reduction occurs
Electrode -A conductor through which electricity enters or leaves an object, substance, or region
Ion -An atom or molecule with a net electric charge due to the loss or gain or more electrons
