Magnetic fields are created during operation and charging electric cars. But how do they affect the human body? A new study explains.
Whether cell phones, radar controls or induction foci: Many devices generate magnetic fields. This also applies to electric cars. But how high is the stress of electromagnetic fields in the interior of the vehicles. And: What influence do you have on the human body? One Current study On behalf of the Federal Office for Radiation Protection (BFS) and the Federal Environment Ministry, answers.
How dangerous are the magnetic fields of electric cars?
For the study, the experts examined the magnetic fields at the seats of 14 different car models from the construction years 2019 to 2021 in different operating states. As the BFS reports, all electrical cars examined have complied with the recommendations for protection against health effects of magnetic fields. In principle, one is not exposed to stronger magnetic fields in pure electric cars than in vehicles with conventional or hybrid drive.
In some cases, comparatively strong magnetic fields were found. “However, the recommended maximum values for fields caused in the body were observed in the examined scenarios, so that no health-relevant effects are to be expected according to the current scientific level of knowledge,” reports BFS President Inge Paulini.
Driving style affects the radiation strength
Magnetic fields arise when electrical currents flow. There are therefore many sources of magnetic fields in modern motor vehicles. Among them: air conditioning systems, fans, electric windows and seat heaters.
In the case of electric vehicles, there is above all a larger and more powerful battery, the high -voltage cabling and the inverter (inverter) for the drive current and the electrical drive itself.
In the study, it turned out that the magnetic fields in the footwell are strongest. In the head and fuselage area, the values were rather low. It also showed that the driving style has an impact on the strength of a magnetic field.
With a sporty driving style with strong acceleration and braking processes, significantly stronger magnetic fields occurred briefly than with a moderate driving style. However, the peak values of the radiation generated were also below the dangerous threshold.
Depending on the construction, various models cut differently in the study. For example, the Mercedes GLE 350 Hybrid showed a higher load. According to Paulini, the manufacturers in their hands would have to reduce local top values with an intelligent vehicle design and to keep average values low.
Largest study on magnetic fields of electric cars
The BFS study is the most extensive and detailed examination of magnetic fields in electric vehicles so far. The data collected is based on systematic field-strong measurements in current vehicle models, which are approved for German road traffic, on roller test benches, on a closed test and test route and in real road traffic.
A total of eleven purely electrically powered cars, two hybrid vehicles and a vehicle with an incinerator were examined. Vehicle manufacturers were not involved in the examination.

As a tech industry expert, I would approach this study with caution and skepticism. While it is important to examine the potential risks of electromagnetic fields emitted by electric cars, it is also crucial to consider the context in which these fields are present and any potential mitigating factors.
It is well-known that electric cars produce electromagnetic fields due to the operation of their electric motors and batteries. However, the level of exposure to these fields is typically much lower than what is considered harmful by current safety standards. In fact, the World Health Organization has stated that there is no conclusive evidence linking exposure to electromagnetic fields from electric cars to adverse health effects.
That being said, it is still important to continue researching and monitoring the potential risks associated with electromagnetic fields from electric cars. This study could be a valuable contribution to the existing body of knowledge on this topic, but it is important to interpret its findings in the broader context of existing research and safety standards.
Overall, while it is important to be mindful of potential risks, it is also important to approach this issue with a balanced perspective and rely on scientific evidence to inform our understanding of the potential health risks associated with electromagnetic fields from electric cars.
