摘要：AbstractThe main purpose of this paper is to present a didactical method as used for an assessment of electromagnetic field effects on the environment. First of all, this paper presents the influence of the electric field on the environment and, after that, the methodology, as used for the efficient transfer of all the results to students, is described. Any electromagnetic equipment working on high voltages makes a significant electromagnetic field around itself. The intensity of that field depends on the voltage type, the voltage level and the distance from the device. It's obvious that a high intensity in this field makes for more drastic effects. Consequently, the effects of this highly electromagnetic field are more likely to be observed around this equipment (e.g. overhead power lines, power stations). These effects are indirect ones, (e.g. ecological pollution, phonic pollution, radio-TV jamming and air ionization), and direct ones, (electromagnetic induction pollution or accidental risks to humans or animals). In the case of nearby overhead power lines or power stations, working on high voltage, electromagnetic phenomena are imposing the need for certain protective measures, both for humans and for the environment, which must be carried out during a safe service. The methodology used for sending this knowledge to students involved three stages: a description of the direct and indirect influences of the electromagnetic field on the environment; the presentation of methods used to produce evidence of the effects of electromagnetic induction, (direct and indirect), in order to prevent accidents; the description of effects (biological and physical) made principally by the electrical field component on the human body. The efficiency of this method is analyzed at the end of this paper, through some real examples.
