Summary[edit]

Description
Македонски: Во сад исполнет со масло е поставена електрода која е прклучена на инфлуентна (електростатско-индукциска) машина. Знаејќи дека маслото е диелектрична средина и практично не дозволува протекување на струја, во зрната од гриз се индуцира диполен момент и тие се подредуваат и ги отцртуваат силовите линии на електричното поле. Подготвено, изведено и објаснето од проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Experiment illustrating electric field lines. An electrode connected to an electrostatic induction machine is placed in a oil-filled container. Considering that oil is a dielectric medium (current is practically zero), dipole moment is induced in the grains (grits) and they are arranged showing the force lines of the electric field. Prepared, performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Expérience illustrant les lignes du champ électrique.
Une électrode est placée dans l'huile et connectée à un générateur de charges électrostatiques. L'huile étant un diélectrique, un moment dipolaire apparaît et oriente les grains de matière selon le champ électrique généré.
Expérience réalisée et expliquée par le professeur Oliver Zajkov de l'Institut de physique de l'université Saints-Cyrille-et-Méthode de Skopje de Macédoine.
Română: Punerea în evidență a liniilor de câmp electric. Un electrod conectat la o mașină de inducție electrostatică este plasat într-un recipient cu ulei. Întrucât uleiul este un dielectric, atunci când curentul împinge sarcini electrice în electrod, particulele se aranjează în așa fel încât prezintă liniile de forță ale câmpului electric. Efectuat de prof. Oliver Zajkov de la Institutul de Fizică al Universității Sfinții Chiril și Metodiu din Skopje, Macedonia.
