Hans Christian Ørsted

Hans Christian Ørsted was a Danish physicist and chemist who is most widely known for observing that electric currents induce magnetic fields, an important aspect of electromagnetism. He shaped post-Kantian philosophy and advances in science throughout the late 19th century.

•Faraday and Henry performed lots of experiments to learn about the connection between electricity and magnetism. The results of these experiments have led to the life styles of today's men, who made life easy by using lots of electrical applications.
The research that established Faraday as the foremost experimental scientist of his day was, however, in the fields of electricity and magnetism. In 1821 he plotted the magnetic field around a conductor carrying an electric current; the existence of the magnetic field had first been observed by the Danish physicist Hans Christian Oersted in 1819. In 1831 Faraday followed this accomplishment with the discovery of electromagnetic induction and in the same year demonstrated the induction of one electric current by another.

•Electromagnetic induction- is the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field.

•They use electromagnet, magnet and galvanometer in their experiment.
