Trumpy: Yes, the neutral and phase do cancel out. This is an issue in DC as well. Car magazines here recently began measuring the EMF in the passenger compartment, along with all the usual tests. For a traditional car, it's not an issue: The battery is in the front and only low currents are used in the wires close to the driver and passengers. However, in latest generation of cars, the engineers have run out of space under the bonnet. Therefore the battery in some cars have now been placed in the trunk. This means that the current needed to start the car (around 100A) pass under the passengers. If the metal frame of the car is used as the return conductor, the EMF reach a high level. Adding a return conductor in parallell with the first reduces the EMF with something like 90%.

No, I don't have any evidence for the Soviet using stronger electromagnetic fields than the West. It was just me being prejudiced again. [Linked Image]
