Abstract

U ovom diplomskom radu bavili smo se problemom gibanja magneta u magnetskom polju. Problemu smo pristupili eksperimentalno za što je bilo potrebno konstruirati mjerni postav. Koristili smo dva permanentna neodimijska magneta, od kojih je jedan bio fiksiran u dnu postolja, dok smo drugi puštali da s neke visine slobodno pada pod utjecajem gravitacijske sile i odbojne sile drugog magneta. Mjerenje smo provodili tako da smo pomoću vrlo preciznog voltmetra očitavali vremena prolaska magneta kroz zavojnicu. S četiri različita pristupa pokusali smo doći do istog cilja, a to je dobiti ovisnost sile među magnetima o njihovoj međusobnoj udaljenosti. Različite metode uspješno su nas dovele do gotovo istih rezultata.

Abstract (english)

In this diploma thesis we studied moving of the magnet in the magnetic field. We wanted to investigate the problem experimentally so the measurement setup was constructed. There were two permanent neodymium magnets, one of them was fixed at the bottom of the stand, while we let other to fall freely under influence of the gravitational force and repulsive force of the first magnet. With very precise voltmeter we measured time needed for magnet to pass through the coil. The goal was to investigate relationship between the force and distance between magnets, and four different methods successfully led us to the almost the same results.
