EMC Question of the Week: August 17, 2026

In an experiment to evaluate the effect of power line fields on mice, the mice are placed in plastic boxes. Some of the boxes are completely covered in aluminum foil, while others have no foil. The boxes are placed 5 cm above a metal plane and 50 cm below a wire. The wire carries 100 amperes of 60-Hz current that returns on the plane. The amplitude of the 60-Hz voltage between the plane and wire is 220 volts. Compared to the mice in the boxes without foil, the mice in the foil-covered boxes are exposed to much weaker      

1. electric fields
2. magnetic fields
3. both of the above
