Michael Faraday's Discoveries and Faraday Flashlight
Michael Faraday (1791 to 1867) is an English chemist and physicist. He is well-known for his pioneering efforts in the study and experiments of electricity and magnetism.
At the age of 21, he was appointed as an assistant to Humphrey Davy in the laboratory of the Royal Institution in London.
Michael Faraday's Contributions in the field of Chemistry
During his initial chemistry-related scientific work, he discovered two new
chlorides of carbon and succeeded in liquefying chlorine and other gases.
1825 was the year Michael Faraday successfully isolated benzene and also the year he was
appointed director of the laboratory.
Faraday gave us the laws of electrolysis in 1834 after conducting countless
experiments on the subject.
Faraday's views on the Conservation of Energy
Michael Faraday held strong views concerning the conservation of energy which led him to
believe that since an electric current could cause a magnetic field,
conversely, a magnetic field should be able to produce an electric current.
He proved this principle of electromagnetic induction in 1831 when he
demonstrated that a moving magnet could induce an electrical current in a
wire coil.
Faraday's principle of induction was crucial in applied science since it
laid the foundation for the dynamo, or generator, which produces electricity
by mechanical means.
No battery flashlight - Application of Faraday's Principle of Electromagnetic Induction
One handy, environmentally-friendly and useful everyday tool that applies Faraday's principle of electromagnetic induction is the no battery flashlight. Since Faraday's flashlight generates its own power and requires no batteries, it is also variously referred to as a no battery flashlight, a batteryless flashlight, a battery-free flashlight or even a shake flashlight.
It is a clean form of energy as all you have to do is to shake the flashlight like you would a pepper shaker.

The Physics Guide
from the manufacturer of the NightStar Faraday Flashlight is an ideal information manual for those fascinated
by the operation of a batteryless flashlight. It contains numerous
equations and diagrams to help explain the nature of magnetism, electronics
and optics. Written for grades 8 and up.
Application of Faraday's Effect in Astronomy
Michael Faraday subsequently discovered, in 1845, that a strong magnetic field has the ability to rotate the plane of polarized light. It is now known as the Faraday Effect. This phenomenon has been used by astronomers and physicists to study galactic magnetic fields. More on astronomy and telescopes.
