Heinrich Lenz, born on February 12, 1804 was a Russian physicist and is mostly remembered for his studies of electromagnetism. At the beginning of the nineteenth century scientists began understanding electricity and magnetism, but not the relationships between the two. Lenz formulated Lenz's Law to study the relationship between the two. Lenz observed that when a electrical current is generated by a changing magnetic field, the magnetic field generated by that electrical current opposes the magnetic field that generated the current.

He was born in Dorpat, Estonia, and studied theology before switching to Physics and Chemistry at the University of Dorpat. He was elected to the Imperial Academy of Sciences at St. Petersburg, where he had presented scientific papers.


Lenz's Law

Lenz's law obeys both the law of conservation of energy and Newton's second law of motion. The law states that when an emf is generated due to change in magnetic flux, the polarity of the induced emf produces a current that's magnetic field opposes the change which produces it.

[math]\displaystyle{ \varepsilon=- {\partial \phi \over \partial t} }[/math]

Where,

[math]\displaystyle{ \varepsilon }[/math] is the induced emf and [math]\displaystyle{ \phi }[/math] is the magnetic flux
