Modelling electromagnetic fields in a two-phase system with Gramme coils for application in magnetic hyperthermia research

The paper presents the results of research related to the design, construction, and implementation of a laboratory setup for the analysis of magnetic hyperthermia generated by a rotating magnetic field (RMF). To designing the magnetic hyperthermia system, a 3D field model was developed using the complex potential method Ω- T 0 and Finite Element Method. Based on the developed field model, the distributions of the magnetic field intensity vector were determined as a function of the current amplitude values within the working area of the system, and the integral parameters of the system were specified, including its resistances and self-inductance as well as mutual inductance. Subsequently, based on the obtained parameter values, a circuit model of the power and control system was developed and implemented. The circuit model was implemented using the LTspice software. Finally, physical tests of the system were conducted, and the measurement results obtained in the constructed prototype system were illustrated.
