I. Introduction
Currently, the electric vehicle was used as the green energy vehicle in many countries and trending to increasing in the future. In 2022, there are the quantity of battery electric vehicle (BEV) up to 18,000 cars compared with 10 years ago in Thailand [1]. For this reason, the charging station have to reserve for the BEV as much as the BEV quantities even in the public area and personal area. Moreover, the charging station can be located on the any area where the electrical power line passed. Therefore, there are a lot of charging station causing the magnetic field surrounding. Consequently, this paper concern about the hazard from the magnetic field expose so that an analysis of the magnetic field while charging electric vehicle under in use of electronic devices especially the mobile phone which is the general electronic device that can be comfortable portable on electric vehicle
