Abstract: of road transport is currently one of the priority areas in science, technology and engineering. One of the most complicated tasks for all manufactures of electric vehicles is the problem of providing electromagnetic safety of users of the cars and ensuring the electromagnetic compatibility of all devices located in the vehicle. In addition there is a concern among citizens and media about the possible health risks and traffic safety due to eff ects of electromagnetic fields, generated by strong currents in the power lines and cables of electric vehicles. It is also noted that such currents and the magnetic fields generated by them may also pose a risk for various electromagnetic compatibility of electrical and electronic equipment of the electric car. In this regards the measuring and evaluation of magnetic fields along with the determination of their topology in the electric car in real time is highly important task. The article present a comparative analysis of the methods for the detection of magnetic fields in an electric car appropriate to identified specific features of these fields. The authors review the task of defining the main characteristics of magnetic field in the electric car. Based on these characteristics the authors concluded that the most perspective magnetic field sensors for the purposes of electromagnetic safety in the electric car are traditional geophysics magnetostatic sensors and modern sensors based on giant impedance.
