In the technological age, electromagnetic (EM) radiation, both natural and human, is found everywhere. Except for the one that carries the necessary information, there is unnecessary EM radiation. These two types of interference occur in the environment, interfering with and producing electromagnetic noises, which are random signals and are not the desired information carriers. To avoid interference, it is necessary to solve the problem of electromagnetic compatibility so that the different electrical devices in the environment would not be harmful to one another. That is why in a number of establishments where human health and safety depend on the proper operation of the equipment – in clinics, in airplanes, in laboratories, etc. - usage of electrical equipment is limited. In order to find the proper way to study these problems and find the best solutions, we offer the investigation of one of the most actual problems in the field of electromagnetic compatibility; specifically, the study of low-frequency magnetic field leakage through Aperture. This study will make a significant contribution to both our knowledge and experience, as well as to one of the most important problems in the field of automotive manufacturing - the interference between electrical and electronic components. Similar tasks have been investigated by EMCOS [1] and are presented in the form of scientific articles [2, 3]. Where the above problem is investigated without additional aperture in the shielding screen. This proposed project offers an examination of the task of low-frequency magnetic field leakage in the presence of aperture in electrical devices and cables.
