Summary

Description
Македонски: Ленцов закон: Придвижување на алуминиумски прстен со помош на електромагнетна индукција, а согласно Ленцовото правило. При вклучување на електромагнетот во околината на прстенот расте магнетниот флукс и во прстенот се индуцира струја, која од своја страна креира магнетно поле. Ова поле е такво да се противи на зголемувањето на причината за неговот постоење (зголемувањето на магнетниот флукс), па затоа прстенот се обидува да излезе од тој простор. При исклучување процесот е обратен, но прстенот повторно се противи на причината за индуцирање на струјата во него. Подготовка, изведба и објаснување: проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Lenz's law: When electromagnet is switched on, magnetic flux around the ring increases, which causes induction of electric current in the ring. This current creates magnetic field, which opposes to the reason for its existence and that is the rise of the flux. That is the reason why the ring tries to "escape" from that place. When the electromagnet is switched off the process is reversed, but still the ring opposes to the reason for induction of current in itself. Prepared, performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Démonstration de la loi de Lenz.
Lorsque le courant électrique est appliqué à l'électroaimant, le flux magnétique autour de l'anneau augmente, ce qui induit un courant dans celui-ci. Ce courant engendre un autre champ magnétique s'opposant au premier (loi de Lenz) et amenant l'anneau à s'éloigner de l'électroaimant. Lorsque le courant est arrêté, le phénomène inverse se produit, ce qui entraîne l'oscillation quand le courant est appliqué et arrêté périodiquement.
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.
