Michael Faraday's Discovery
1821
Michael Faraday discovered that when a magnet is moved inside a coil of copper wire, a tiny electric current flows through the wire.

Discovery of Magnetic Fields Caused by Electricity
1820
Hans Christian Oersted found that when electricity flows through a wire, it produces a magnetic field that affects the needle of a nearby compass.

During a huge storm, Benjamin Franklin Bell flew a kite. The negative charges of the strom was passed onto the kite. The charge went through the string of the kite, and then onto the key that was at the bottom of the kite. Franklin was unaffected by the negative charges because he was holding a dry silk string which insulated him from the charges on the key. When he touched the key, a spark jumped from the key to his body and he received a shock. This is because the negative charge from the key were so strong that it was attracted to the positive charge of his body. By tying a key onto a kite string during a storm, Benjamin Franklin proved that static electricity and lightning were the same.

Stephen Gray
1729
Stephen Gray (December, 1666 - 7 February 1736) was an amateur astronomer, who was the first to systematically experiment with electric conduction, rather than simple generation of static charges and investiagations of the static phenomena.

Francis Hauksbee created electrical effects by putting some mercury into a glass globe, pumping out the air and then spinning it. When he did this in the dark, and then rubbed the globe with his bare hand, it glowed.
