The concept of magnetic field in the high school education

Magnetizam je jedan od najbitnijih koncepata u fizici. Vrlo je bitno da učenici u potpunosti shvate koncept magnetizma i magnetskog polja. U ovome diplomskom radu proučavat će se načini poučavanja koncepata magnetskog polja pomoću silnica. Izradit će se i metodički obraditi pokusi u kojima će se koristiti ferofluid, željezna piljevina i računalo. Koristeći ferofluid, pjenaste ploče, staklene plohe i staklenu bocu izradit će se interaktivno povećalo i detektor magnetskog polja, dok će za pokuse sa željeznom piljevinom biti potrebna bakrena žica, ploče pleksiglasa, odnosno mineralno ulje, staklenka i plastična boca. Svi navedeni materijali su širokodostupni. Od alata potrebna će biti bušilica, skalpel, pištolj za vruće ljepilo i lemilica. Ostalim dijelovima postava pokusa, poput magnetskih iglica, napajanja, baterija, zavojnica, žica i krokodil štipaljkama, je opremljena većina kabineta fizike.Magnetism is one of the most important concepts in physics. It is very important for students to completely understand the concept of magnetism and magnetic fields. Ways of studying magnetism with magnetic field lines will be studied in this thesis. By using ferrofluid, iron fillings and computer resources, a set of experiments will be constructed and methodically prepared for use in class. Interactive magnetic field magnifier and the detector will be constructed by using ferrofluid, foam boards, glass sheets and glass bottle. Copper wire, plexiglass sheets, mineral oil, mason jar and plastic bottle will be used to construct apparatus for experiments with iron fillings. All of the above mentioned materials are easily obtained at hardware stores. Required tools are hand drill, box cutter, hot glue gun and soldering iron. Rest of the required equipment, like magnetic needles, power supply, batteries, inductors, wires and alligator clips, are commonly found in every physics lab
