U ovom radu je objašnjen pojam remanentnog magnetskog toka. Opisan je laboratorijski sustav i postupak mjerenja, te su prikazani rezultati mjerenja. Nakon mjerenja vršio se proračun te su određena četiri parametra i objašnjena je njihova moguća upotreba.This paper explains the concept of residual magnetic flux. Laboratory system, and the measurement procedure are described, the measurement results are shown. After the measurment the calculation was performed and four parameters were determined and their possibility of use was explained. Everything is shown in the pictures, and the values are written in tables
