Impact of a Strong Electromagnetic Field on Rebars in a Reinforced Concrete Building : Design Guidelines and Safety Assessment

To design installation close to high-power AC electromagnetic device, a prediction of the electromagnetic coupling may be mandatory. The present device is composed of different high current multi-turn coils located near the installation, a conductor mesh. This study investigates the self-inductances of the different coils and the mutual inductances to assess the electromagnetic coupling within the installation.

Besides, the study also focuses on the Eddy currents (induction currents) in the conductor mesh around the coil: such currents can be rather large if the appropriate precautions are not used. Such large current may create unwanted significant heat rise in the mesh: it is induction heating. Construction guidelines are then identified and used to design a safe installation.
