1791-1867

EARLY CHILDHOOD Faraday was born in 1791 Grew up near London in

slums known as Newington Butts

His father was a blacksmith Family was poor Had very little education Physically weak

LIFE AS A BOOKBINDER Physical handicap led him to

bookbinding Apprentice to master Georges

Reibau Reading and bookbinding Encyclopedia Brittannica and

Conversations on Chemistry Sir Humphry Davy

FARADAY AS A YOUNG MAN

ASSISTANT TO DAVY Royal Institution Laboratory

Assistant Trip to Italy Meeting with other Scientists Return from the Continent Promotion to Superintendent

FARADAY’S BREAKTHROUGH

1831 Faraday starts research on electricity and magnetism

Experiments with coils of wire around an iron ring

Observes the changes in galvanometer induced by electric current

IRON RING

DISCOVERIES

Electromagnetic Induction Electrical field and electrical currents

How could he continuously create this phenomena?

THE NEXT STEP Faraday devised an experiment set-

up to continuously change magnetic field

Puts a spinning copper disk between the poles of a magnet

Wires attached to disk and galvanometer

Motion converted to electrical energy

FARADAY’S ELECTRIC GENERATOR

IMPORTANCE OF HIS DISCOVERY

The electric generator allowed for electric energy to be produced without the consumption of chemical energy

Using turbines to produce electricity Using water, steam, coal, oil, wind to

power turbines Electricity on a larger scale

MODERN ELECTRIC TURBINE
