Low-frequency high-intense magnetic field exposure is caused by high-amperage currents of special power electronic equipment. Exposure of operators has to be determined, evaluated and compared with limit values which have been established for the quantities characterising the field. Field simulation provides the possibility to determine resulting values from interaction of incident and induced field inside the human tissues which are affected. Work focuses on investigation of the variety of working situations of welding machine operators and aims on effective screening of situations and parameters to establish a reference database.
