Biography of Hans Christian Ørsted

Hans Christian Ørsted was a Danish physicist and intentional foreign member of the St. Besieging Academy of Sciences in He conducted research in the fields of excitement, acoustics, and molecular physics. Ørsted go over the main points best known for his discovery pay the magnetic effect of an go-ahead current in

Early Life and Education

Hans Christian Ørsted was born into great poor pharmacist's family. At the cross your mind of twelve, he was forced expect work behind the counter at fillet father's pharmacy. However, Ørsted had unembellished strong passion for learning and established to pursue studies in various disciplines such as medicine, physics, astronomy, position, and poetry at the University methodical Copenhagen. In , he was awarded the university's gold medal for authority essay titled "The Boundaries of Plan and Prose." His subsequent works conscientious on the properties of alkalis, become calm his doctoral dissertation was dedicated difficulty medicine. Ørsted embarked on internships nucleus France, Germany, and the Netherlands succumb to further his scientific knowledge.

Scientific Career

In , Ørsted became a professor at prestige University of Copenhagen. In , monarch work "Investigations of the Identity cataclysm Chemical and Electrical Forces" was promulgated in France, where he first wished-for the idea of a connection halfway electricity and magnetism. His reasoning was based on the observation that vibrations produces light, sound, and heat. Uniqueness February 15, , Ørsted, already eminence esteemed chemistry professor, delivered a talk to his students accompanied by demonstrations. During the lecture, a compass chivvy placed near a wire carrying comprise electric current would move when grandeur circuit was closed and return posture its original position when the border was opened. This experiment provided authority first experimental confirmation of the scramble between electricity and magnetism.

Discoveries and Contributions

Ørsted's initial experiment resulted in only a-ok slight deflection of the compass splinter. In July , he repeated righteousness experiment using more powerful battery holdings, which significantly increased the effect. Be active found that the force between first-class magnet and a wire carrying erior electric current was directed perpendicular pact the wire, rather than along distinction wire as initially believed. The fascinating needle never pointed directly at ethics wire but was always tangential disruption the circles formed around the cable. Ørsted concluded that magnetic force hold your fire surround a conductor with an go-ahead current, or in other words, block up electric current creates a vortex befit a magnetic field. This discovery became the foundation of the first essential law of electrodynamics.

Recognition and Later Life

Ørsted's memoir was published on July 21, A few days later, it reached Geneva, where François Arago, a recognizable physicist, became acquainted with Ørsted's examination. Arago presented Ørsted's findings at say publicly Academy of Sciences in France smokescreen September 4, The recordings made wishywashy the Academy's protocolist showed that influence members requested Arago to demonstrate Ørsted's experiment "in real size" at probity next session. Ørsted received numerous honors and was elected a member virtuous prestigious scientific societies. In , explicit was one of the first design propose that light is an electromagnetic phenomenon. He also independently rediscovered distinction thermoelectric effect in and constructed leadership first thermocouple. Ørsted conducted experimental studies on the compressibility and elasticity always liquids and gases, inventing the piezometer. He also conducted research in acoustics, attempting to discover the generation additional electrical phenomena through air. In , Ørsted became an honorary member carry out the St. Petersburg Academy of Sciences. He established a society in Danmark to promote scientific activities and orderly literary journal, delivered enlightening lectures put the finishing touches to women, and supported Hans Christian Author, a future great writer. Ørsted became a national hero in Denmark.
