6 5  LENZ’S LAW AND CONSERVATION OF ENERGY
In 1834, German physicist Heinrich Friedrich Lenz (1804-1865) deduced
a rule, known as Lenz’s law which gives the polarity of the induced emf
in a clear and concise fashion The statement of the law is:
The polarity of induced emf is such that it tends to produce a current
which opposes the change in magnetic flux that produced it
