In the late nineteenth century, the work of scientists like Faraday(1791-1867), Gauss(1777-1855), Ampere(1775-1836), Lorentz (1853 - 1928) and especially Maxwell(1831-1879), ended up doing unification of electric and magnetic phenomena. Because of this unification, the events related to these two areas began to be associated with what we call electromagnetism. Equation 2 shows the Lorentz force, which acts on particles subjected to electromagnetic fields. The first term is linked to Colombian forces. Depending on the sign of the charge, this force can be attractive or repulsive, the constant k is worth 8.99 x 10 Nm The second term is linked to the movement of loads, with a velocity v in a magnetic field B. ACTIVITY Physics As the electric field vector is subjected to a load q at any point in space is given by Combining with the first term of equation 2 to Lorentz force is written as: vB Where: q The first term of the equation is connected to the electric field produced by the charge q at a point distant from the charge q Comparing equations 1 and 2, you may notice some similarity of the role of the load in relation to the electromagnetic force, and the role of mass in gravitational force? Will these two entities have anything to do with the stability of matter? Also, compare the constant K with G. What can you say about the intensity of the electromagnetic and gravitational forces. Until the late nineteenth century, physicists viewed the universe based on the mechanical model of Newton, which established the universe as a machine, in which the forces and matter that act as gears. Radiation were understood as that constituted by electromagnetic waves, oscillations of electric and magnetic fields, which are propagated according to the four Maxwell laws. The wave nature of light was understood by means of electromagnetism, it was understood that light was a wave that combined electric and magnetic fields. Experimental work of the late nineteenth century indicate further that the wave nature, also a granular nature to light. The grains of light are called photons, and would like packets of energy. Now, if the light is a result of the combination of electric and magnetic fields, one would assume that these fields were also granular. Thus, the works presented in the first half of the twentieth century led to the idea that the events related to electromagnetism occurred through the exchange (emission and absorption) of photons between charges. But the forces that keep everything in its place? Best keep reading! The three fundamental interactions

Krajem devetnaestog stoljeća, djelo znanstvenika poput Faraday(1791-1867), Gaussa(1777-1855), Amper(1775-1836), Lorentz (1853 - 1928), a posebno Maxwell(1831-1879), zavrsilo radiš Ujedinjenje električnih i magnetskih pojava. Zbog tog ujedinjenja, događaji vezani uz ta dva područja počeli biti povezan s onim što mi zovemo elektromagnetizam. Jednadžba 2 pokazuje Lorentz silu, koja djeluje na čestice izloženi elektromagnetskim poljima. Prvi termin je povezan s kolumbijskim snaga. Ovisno o predznaku naboja, ta sila može biti privlačna ili odbojna, konstanta k je vrijedan 8,99 x 109 Drugi pojam je povezan s kretanjem opterećenja, s brzina v u magnetskom polju B AKTIVNOST Fizika Kao vektor jakosti električnog poljaE je podvrgnut opterećenju q1 u bilo kojoj točki u prostoru dajeF Kombinirajući s prvog mandata od dvije jednadžbe na snagu Lorentz je napisana kao: QE Gdje: q1 Prvi član iz jednadžbe je priključen u području proizvedeni točkastog naboja q1 udaljena naboja q2. Uspoređujući jednadžbi 1 i 2, možda ćete primijetiti neke sličnosti ulozi opterećenja u odnosu na elektromagnetske sile, kao i ulogu mase u gravitacijskom silom? Hoće li se te dvije osobe imaju bilo kakve veze sa stabilnošću materije? Također, usporedite konstantu K G. Što možete reći o intenzitetu elektromagnetskih i gravitacijska sila. Do kraja devetnaestog stoljeća, fizičari su pogledali svemir temeljiti na mehaničkom modelu Newtona, koji je uspostavio svemir kao stroj, u kojem su snage i tvari koje djeluju kao zupčanika. Zračenje se shvatiti kao da je sastavljen od elektromagnetskih valova, oscilacije električnog i magnetskog polja koje se prenose u skladu s četiri Maxwellove zakona. Valne prirode svjetlosti je razumio kroz elektromagnetizma, što je shvatio da je svjetlost val koji u kombinaciji električnih i magnetskih polja. Eksperimentalni rad od kraja devetnaestog stoljeća pokazuju nadalje da je val priroda, i zrnati priroda na vidjelo. Zrnca svjetlosti nazivaju se fotoni, a željeli paketića energije. Sada, ako je svjetlost rezultat kombinacije električnih i magnetskih polja, jedna bi se pretpostaviti da su ove stavke su također granulama. Dakle, radovi prikazani u prvoj polovici dvadesetog stoljeća dovela do ideje da su događaji vezani uz elektromagnetizma dogodila kroz razmjenu (emisija i apsorpcija) fotona između punjenja. Ali snage koje drže sve na svoje mjesto? Najbolje nastavite čitati! Tri temeljne interakcije221
