In his search for knowledge, Faraday was fortunate enough to attend some of Sir Humphrey Davy's lectures on science at the Royal Institution. Davy's lectures interested Faraday so much that he took down complete notes, a copy of which he later bound and sent Sir Humphrey.
Davy, after reading the notes, offered young Faraday a position as laboratory assistant at a salary of about $10.00 per week. Nothing could have been more fortunate than this connection with Sir Humphrey Davy for here was the beginning of an epoch of experimental science.
At this time, the principles of electricity were just being discovered. On Christmas Day, in 1821, while he was showing an experiment to his wife, Faraday got the idea that turned out to be the basic principle of all electric generators and motors. It took months of experimenting before he could prove that the principle was correct.
