Абстракт

This paper presents a comprehensive investigation of linear electric circuits with inductively coupled coils, focusing on the analysis of mutual inductance (M) and the coupling coefficient (k). The study begins with a theoretical overview, including the fundamental principles of electromagnetic induction and the mathematical relationships describing the behavior of inductively coupled coils. Experimental setups were used to explore the influence of key parameters, such as the distance between the coils and the angle between their planes, on the values of M and k. The results demonstrate a clear dependence of mutual inductance and coupling coefficient on these parameters, with mutual inductance decreasing as the distance between the coils increases or as the angle between their planes approaches 90°. The measured data are combined with mathematical calculations to validate the accuracy of the experiments. The conclusions drawn from this study provide useful tips into the optimization of inductively coupled coil systems, which are widely used in power transmission, signal processing, wireless energy transfer, and electromagnetic sensor applications. These findings can be applied in the design and analysis of efficient electromagnetic devices.
