To determine the magnetic field levels in the passenger
compartment, measurements were performed in all four
seats at three heights (feet, chest, and head) in the abovementioned
hybrid cars. Because the magnetic flux density
values change constantly as the car travels along, following
the functioning sequence of the gas engine and the electric
motor, measurements were performed in four different
driving conditions: stationary (idling) and traveling at
20–40 km/h, 80–120 km/h, and over 120 km/h (high-speed
cruising—in some cases).
