The integration of Vietnam’s economy in recent years has resulted in increasing demand of electricity, with the establishment of many ultra-high-voltage transmission lines leading to various load centers. Therefore, many of the effects of these lines on inhabitants need to be considered. The negative impacts of industrial frequency of magnet fields on humans and the environment are matters of concern for scientists as well as for domestic and international organizations. For this reason, the calculation of magnet fields of transmission lines, especially, super high voltage lines, is of paramount importance in the determination of magnet field influences. This paper presents the method for calculating magnet fields on electricity wire lines and some measures and solutions for the reduction of negative impacts of these fields will also be discussed.
