The truth is that electricity has always been around because it naturally exists in the world. Lightning‚ for instance‚ is simply a flow of electrons between the ground and the clouds. When you touch something and get a shock

Page proposed a reciprocating analogue of the steam engine (1850); and H. Wilde made the commercially successful Alliance generator (1866) for powering arc lamps in lighthouses. (An interesting side note: much of the clever work to improve generators was done by instrument makers‚ such as E.M. Clarke of London‚ who used galvanic current to "cure" illnesses.) All of these generators employed permanent magnets. • Ampère/Pixii’s generator • Page’s generator • Wilde’s lighthouse generator 1866 Werner

Electrostatic Field • An electrostatic field is a phenomenon that is very similar to a magnetic field. When an object is electrically charged‚ it creates an electrostatic field. If an object has an excess of electrons‚ then it’s considered to have a negative charge. If an object has fewer electrons than its surrounding environment‚ though‚ it’s considered to be positively charged. Just like with magnetic fields‚ two objects that are oppositely charged will attract each other. This scientific
