Feasibility of estimating in-service vehicle occupant exposure to electrical powertrain magnetic fields using non-local magnetic field measurements

In-service monitoring of magnetic field emissions from vehicle electrical powertrain components could provide useful information relating to the development of possible faults. Such changes may also have implications for human exposure to low frequency magnetic fields, but the permanent installation of magnetic field sensors in occupant locations is not practicable. This paper outlines a simulation-based investigation of issues relating to the estimation of occupant exposure to magnetic fields using magnetic field measurements made in the vicinity of powertrain components and identifies processing implications.
