What was discovered
Faraday proposes that electric and magnetic forces act through lines of force that fill space and have physical reality, and discovers diamagnetism and the Faraday effect. He replaces action at a distance with the field.
'On the Physical Character of the Lines of Magnetic Force' (1852).
