Македонски: Опит кој ја прикажува Амперовата сила со која си дејствуваат магнет и спроводник низ кој тече постојана струја. Во првиот случај насоката на магнетното поле е надолу (од север кон југ), а насоката на течење на струјата низ подвижниот спроводник е од лево кон десно, нормално на магнетното поле. Согласно Флеминговото правило на левата рака, се појавува сила која дејствува на спроводникот во насока нормална на полето и насоката на течење на струјата, па затоа спроводникот се поместува. Ако се смени насоката на полето, ќе се смени и насоката на дејството на силата. Со промена на насоката на течење на струјата, повторно се менува насоката на векторот на силиата. Подготвено, изведено и објаснето проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Demonstration of Ampère's force law. The force acts between тhe magnet and the wire through which electric current flows. In the first case the magnetic field is directed downward, the direction of the current is perpendicular to the magnetic field, from left to right. According to the Fleming's left hand rule, force is created, which acts on the wire in the direction perpendicular to magnetic field and current. It makes the wire to roll. If the direction of the magnetic field is changed, the force direction changes also. The same effect has the change of the direction of current. 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 force d'Ampère.
Le passage du courant électrique dans les tiges de cuivre entraîne la création d'un champ magnétique. L'interaction entre ce dernier et le champ magnétique de l'aimant entraîne une force selon la règle de la main gauche. 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. Български: Демонстрация на Закона на Ампер, действащ между два успоредни проводника, през които протича постоянен ток. Ако те имат една и съща посока - има сила на привличане, но ако посоките са противоположни - наблюдва се сила на отблъскване.
