Workers exposition near electromagnetic forming process: an experimental and simulation study.

Electromagnetic forming is an industrial process using pulsed magnetic field for shaping conductive material. With reference to the European Directive 2013/35/UE, evaluating the electromagnetic safety of workers seems overriding. Experiments and simulations were combined to determine the interaction between the source and working environment. An experimental map of the radiated field was obtained for an input signal with frequency components lower than 20 kHz. Electromagnetic simulations of the system were validated thanks to experimental measurements. The electric field in an equivalent body tissue cylinder was then calculated and compared to the limit values defined in the Directive. Locations at risk were finally determined.
