The potential health effects of electric and magnetic fields (EMFs) from power substations and transmission lines, particularly in residential areas, have been a subject of ongoing debate and research. While EMFs are produced whenever electricity is generated, transmitted, or used, their impact on human health, especially regarding cancer risks like juvenile leukemia, remains controversial. When measuring electromagnetic fields near transmission lines, Gauss meters yield useful data on the amount of magnetic field exposure. This data can be used to identify potential health and safety risks and, if necessary, to guide the implementation of suitable mitigation measures. These empirical correlations, once established and verified, offer a useful tool for approximating the intensities of electric and magnetic fields at different separations from transmission lines without requiring a lot of data. They can be applied in risk assessments, regulatory compliance, and urban planning to reduce the possibility of exposure to electromagnetic fields posing a health and safety issue. Studies and assessments conducted by organizations like ICNIRP help in ensuring that potential risks associated with EMF exposure are minimized and managed effectively. The potential harmful effects of low-frequency electric and magnetic fields on human health have garnered increasing attention, particularly those generated by high-voltage (HV) power transmission lines. This study investigates these effects by calculating the electromagnetic fields generated near HV power lines using the COMSOL Multiphysics software. The results demonstrate the accuracy and effectiveness of these modules in modeling electromagnetic fields. Comparisons with the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines reveal that the calculated fields fall within safe limits, thereby validating the approach and contributing valuable insights to the ongoing discussion on electromagnetic field.
