Oersted behind Maxwell's theory

Oersted behind Maxwell's theory

It takes place in Denmark in 1820 ... In an old shack lost in the forest ... It is night ... The storm brewing in the distance and the wind blows ... In this house, a man dealing with his work table: it is Hans Christian Oersted. What is it? Unspeakable experiences? 

No. He simply pass current in son, as do some time since a lot of physicists on the planet. But for him, this cold stormy night, these experiences will have an insignificant effect unexpected, a mysterious effect, whose impact on our civilization will be huge! He realizes indeed a compass placed not far away sees the needle deviate from its position, highlighting a remote influence. 

So far, only a magnet could change the position of the needle. There Oersted highlighted a real influence distance created by the mere passage of current in a wire!

He had, without knowing it, placing the first stone of electromagnetism, a theory which will be finalized by Maxwell . 

Maxwell and in doing so, unifying electricity and magnetism, the open road, without knowing either, one of the greatest adventure of all time, the great unification, the Holy Grail of modern physics! 

And it will also allow engineers and technicians to create technological marvels, without which modern man said could no longer survive: electric motors fitted to virtually all objects of daily life, alternators, which can easily produce current , cycling the power plant, but also induction, radio, television, mobile phone, wifi, and so on and best ...

Oersted So really, but unknowingly, as Monsieur Jourdain, changed the world.
