The Greatest Physics Discoveries 1. The Law of Falling Bodies (1604) Galileo Galilei overturns nearly 2000 years of Aristotelian belief that heavier bodies fall faster than lighter ones by proving that all bodies fall at the same rate. 2. Universal Gravitation (1666) Isaac Newton comes to the conclusion that all objects in the universe, from apples to planets, exert gravitational attraction on each other. 3. Laws of Motion (1687) Isaac Newton changes our understanding of the universe by formulating three laws to describe the movement of objects. 1) An object in motion remains in motion unless an external force is applied to it. 2) The relationship between an object's mass (m), its acceleration (a) and the applied force (F) is F = ma. 3) For every action there is an equal and opposite reaction. 4. The Second Law of Thermodynamics (1824 -- 1850) Scientists working to improve the efficiency of steam engines develop an understanding of the conversion of heat into work. They learn that the flow of heat from higher to lower temperatures is what drives a steam engine, likening the process to the flow of water that turns a mill wheel. Their work leads to three principles: heat flows spontaneously from a hot to a cold body; heat cannot be completely converted into other forms of energy; and systems become more disorganized over time. 5. Electromagnetism (1807 -- 1873) Pioneering experiments uncover the relationship between electricity and magnetism and lead to a set of equations ...

As it often happens, the invention of the electric motor was not accomplished by one person. Gradual process of development initiated by the discovery of electromagnetism by Hans Oersted in 1820, the first of which was the Faraday's motor.

Check us out at www.tutorvista.com A galvanometer is a type of ammeter: an instrument for detecting and measuring electric current. It is an analog electromechanical transducer that produces a rotary deflection of some type of pointer in response to electric current flowing through its coil. The term has expanded to include uses of the same mechanism in recording, positioning, and servomechanism equipment. The deflection of a magnetic compass needle by current in a wire was first described by Hans Oersted in 1820. The phenomenon was studied both for its own sake and as a means of measuring electrical current. The earliest galvanometer was reported by Johann Schweigger at the University of Halle on 16 September 1820. André-Marie Ampère also contributed to its development. Early designs increased the effect of the magnetic field due to the current by using multiple turns of wire; the instruments were at first called "multipliers" due to this common design feature. The term "galvanometer", in common use by 1836, was derived from the surname of Italian electricity researcher Luigi Galvani, who discovered in 1771 that electric current could make a frog's leg jerk. Originally the instruments relied on the Earth's magnetic field to provide the restoring force for the compass needle; these were called "tangent" galvanometers and had to be oriented before use. Later instruments of the "astatic" type used opposing magnets to become independent of the Earth's field and would operate ...

The pictures which accompany this piece are of the Danish physicist Hans Christian Oersted (1777-1851). It was he who discovered the connection between electricity and magnetism, followed up by Arago and Davy. When Johann was searching for a new title, he, like his father before him chose a title befitting a new innovation or invention - how best to be remembered rather than the prosaic 'Polka in F or G or whatever'? Therefore, this polka 'Electromagnetism' - first performed for a ball of the technical students at Vienna University on 11th February 1852 - the title simply one of many Johann could have selected from a wide variety of scientific terminology.

©2009 edumation.org An educational Flash animation by Mustafa Daif celebrating Oersted's birthday on August 14th, 2009. In 1820, the Danish scientist Hans Christian Oersted (1777-1851) discovered that there was a relationship between electricity and magnetism. While preparing for a lecture, he noticed that a compass deflected from the magnetic north when a current-carrying wire was placed near the compass. He concluded that electricity produced magnetism. He used Alessandro Volta's (1745-1827) battery. After 11 years of Oersted's discovery, Michael Faraday (1791-1867), building upon Oersted's discovery, discovered that magnetism could produce electricity. The works of Volta, Oersted and Faraday paved the way for understanding the nature of electricity.

Em 1820, um físico dinamarquês chamado Hans Christian Oersted aproximou um fio transportando corrente elétrica de uma bússola. Naquele instante, começou a se descobrir a íntima ligação que existe entre a Eletricidade eo Magnetismo. Por este motivo, este é considerado por alguns o experimento mais importante da História. Você pode reproduzí-lo com menos de R$ 10,00, basta uma pilha de 1,5 V, um clips de papel e uma bússola.
Este segundo procedimiento en el experimento de HANS CHRISTIAN OERSTED es igual al anterior, que ya hemos visto, pero sustituyendo el conductor uní-filiar por una bobina al aire de 12 cm. de diámetro por 10 de longitud de hilo de cobre esmaltado. Colocada la aguja imantada en el centro de la bobina, cuando hacemos circular la corriente por el circuito la aguja responde, llegado a girar en su eje. Como hemos explicado en el video anterior de Oersted, la aceptación de la componente magnética asociada a las corrientes eléctricas que pretende confirmar este experimento, se debió, a que, la respuesta de la aguja imantada, se caracteriza por tener criterios magnéticos y no eléctricos. "Schweigger" con un experimento parecido descubrió el "multiplicador" conducente a los aparatos de medida.
HANS CHRISTIAN OERSTED (1777-1851) Tenemos aquí el experimento de Oersted, se trataba de comprobar que en la corriente eléctrica estaba incluida una componente magnética. La cosa no era fácil, ya que cuando aproximamos a la brújula un campo eléctrico la aguja lo detecta y se mueve. Por ello bien podía ser que al circular la electricidad por el conductor, fuese únicamente la electricidad la que hacia que se moviera la aguja, con lo cual la teoría presente entre los investigadores, de la componente magnética asociada a la electricidad no era valida. Si aproximamos un imán la aguja también reacciona y se mueve, pero se mueve de diferente manera que en el caso anterior de la electricidad. Puesto que el imán atrae a la brújula, orientándola en sentido inverso de sus respectivas polaridades y al invertir el imán, la brújula gira 180º, ofreciendo el otro polo. En el caso de cuando hemos aproximado una carga eléctrica a la brújula, la atrae, sin diferenciar los polos magnéticos de dicha brújula; lo mismo por el polo norte que por el sur que por el centro La brújula en el experimento de Oersted responde al criterio del magnetismo, se orienta como influenciada por un campo magnético. Nada más hemos de invertir la circulación de la corriente y la brújula gira 180 º. Con ello quedo demostrado que existía una componente magnética al circular una corriente eléctrica.
