Michael Faraday (/ ˈ f ær ə d eɪ,-d i /; 22 September 1791 – 25 August 1867) was an English physicist and chemist who contributed to the study of electromagnetism and electrochemistry.
In 1824 he observed what has been called rotatory magnetism, and that most conductive bodies could be magnetized; these discoveries were completed and explained by Michael Faraday (1791–1867). In 1834, Emil Lenz stated Lenz's law , which says that the direction of induced current flow in an object will be such that its magnetic field will ...
Michael Faraday holding a piece of glass of the type he used to demonstrate the effect of magnetism on polarization of light, c. 1857.. By 1845, it was known through the work of Augustin-Jean Fresnel, Étienne-Louis Malus, and others that different materials are able to modify the direction of polarization of light when appropriately oriented, [4] making polarized light a very powerful tool to ...
If a system is static, such that magnetic fields are not time-varying, then by Faraday's law, the electric field is curl-free. In this case, one can define an electric potential , that is, a function φ {\displaystyle \varphi } such that E = − ∇ φ {\displaystyle \mathbf {E} =-\nabla \varphi } . [ 15 ]
Michael Faraday developed the concept of lines of force to describe electric and magnetic phenomena. [13] In 1831, he writes [13] By magnetic curves, I mean the lines of magnetic forces, however modified by the juxtaposition of poles, which would be depicted by iron filings; or those to ·which a very small magnetic needle would form a tangent."
