Abstract

Induktivno zagrijavanje je proces zagrijavanja električki vodljivih materijala pomoću elektromagnetske indukcije. U materijalu koji se postavi u visokofrekventno izmjenično magnetsko polje inducira se izmjenična elektromotorna sila koja uzrokuje vrtložne struje. Kako materijal ima otpor, zbog protjecanja struje se zagrijava. Diplomski rad bavi se opisom efekta, izradom uređaja za indukcijsko zagrijavanje i demonstracijom rada istog te mjerenja korisnosti uređaja. Indukcijsko zagrijavanje posebno je zanimljivo i s edukacijskog gledišta jer se materijal grije bez kontakta temeljem efekta koji se uči, ali često vrlo slabo razumije, u srednjim školama.

Abstract (english)

Induction heating is a process of heating electrically conductive materials by electromagnetic induction. In material, that is placed into an alternating magnetic field of high frequency, the electromotive force is induced causing eddy currents. The material is heating up due to its electrical resistivity. In this diploma thesis the process of induction heating is described. For the purpose of the thesis a device for induction heating has been built and its functioning demonstrated. The efficiency of the device was measured by heating up different materials. Induction heating is specially interesting also from the educational point of view. The ability of heating an object without a direct contact has the basis in an effect that is taught in high schools but is often poorly understood by pupils.
