Physics ACTIVITY And in the case of the bicycle dynamo, who provides energy? The figure represents the schema generator: basically, it consists of a rectangular loop which is immersed in a uniform magnetic field and rotates around an axis perpendicular to the magnetic field lines. The phenomenon of electromagnetic induction led to a revolution in the production of electricity, which until then was only obtained from the chemical energy of the battery or batteries. The importance of studies of Faraday is among the five important dates that the historian Eric Hobsbawm cites to analyze, in his book The Age of Revolution, the periodfrom 1789 to 1848. On the whole, the classical physical sciences have not been revolutionized, ie remained substantially within the terms of reference established by Newton, or continuing research lines already followed in the eighteenth century or expanding old ones discovered fragmentary coordenadoas broader theoretical systems. Thus, the most important new fields open, and the only technology that has immediate consequences was the electricity, or rather of electromagnetism. Five key dates - four of them in our time - mark your progress decisive: in 1786, when Galvani discovered the electric current; 1799, when Volta constructed his battery; 1800, when the electrolysis was discovered; 1820 when Oersted discovered the connection between electricity and magnetism; 1831 when Faraday established the relationships between all these forces, and by chance found himself as the pioneer of an approach of physics (in terms of "fields" instead of mechanical impulses) that anticipated the modern era. (HOBSBAWM , p.388) Electricity cause a revolution ... In the eighteenth century, the industrial revolution was the emergence of the factory system (Steam and move the text, the teacher Luiza Polak, you can find more information about it). This revolution occurred over the work and dedication of technicians than scientists. The nineteenth century was the time of the great syntheses of electromagnetism, which contributed to the emergence of a second industrial revolution. The difference of this second revolution in relation to the first is that it now is because scientific development, fostered Generation Transformation equal to Energy Conservation

Fizika AKTIVNOST I u slučaju bicikl dinamo, koji daje energiju? Brojka predstavlja shema generatora: u osnovi, sastoji se od pravokutnog petlje uronjenog u odori magnetskom polju i vrti se oko osi okomite na silnice magnetskog polja. Fenomen elektromagnetske indukcije dovelo do revolucije u proizvodnji električne energije, koja je do tada samo je dobio od kemijske energije baterije ili baterija. Značaj studija Faraday je među pet važnih datuma da je povjesničar Eric Hobsbawm CITES za analizu, u svojoj knjizi The Age of revolucije, razdoblje1789-1848. U cjelini, klasične fizičke znanosti nisu revoluciju, odnosno ostala suštinski unutar projektnog zadatka utvrđenih Newton, ili nastavak istraživanja reci već slijedi u osamnaestom stoljeću ili proširiti stare otkrio fragmentarni coordenadoas šire teorijske sustave. Dakle, najvažnije nove stavke otvorene, i jedina tehnika koja ima neposredne posljedice bio struja, odnosno elektromagnetizma. Pet ključnih datuma - četiri od njih u našem vremenu - obilježiti vaš napredak odlučan: 1786, kada je Galvani otkrio je električna struja; 1799, kada je Volta izgrađene svoju bateriju, 1800, kada je elektrolizom je otkriveno 1820 kada Oersted otkrio vezu između elektriciteta i magnetizam;. kada je 1831 Faraday uspostavljena odnosa između svih ovih snaga, a slučajno našao kao pionir pristupa fizike (u smislu "polja" umjesto mehaničkih impulsa) koji predviđa moderno doba (Hobsbawm , p.388) Struja izazvati revoluciju ... U osamnaestom stoljeću, industrijska revolucija bila je pojava tvorničkog sustava (parni i premještanje teksta, nastavnik Luiza Polak, možete pronaći više informacija o tome). Ova revolucija dogodila nad radom i zalaganjem tehničara od znanstvenika. Devetnaesto stoljeće bilo je vrijeme velikih sinteza elektromagnetizma, što je doprinijelo nastanku drugi industrijske revolucije. Razlika ove druge revolucije u odnosu na prvi je da je sada, jer znanstveni razvoj, poticati Generacija Transformacija jednak Energy Conservation159
