A comprehensive study commissioned by Germany’s Federal Office for Radiation Protection (BfS) and the Federal Ministry for the Environment (BMUV) has concluded that electric vehicles (EVs) do not pose a greater health risk from magnetic fields compared to conventional combustion engine cars.
Measurements and computer simulations across 14 vehicles—including battery-electric, hybrid, and combustion models—found all vehicles complied with recommended limits for electromagnetic field exposure. According to the BfS, this is the most extensive investigation of its kind to date.

“Comparatively strong magnetic fields were detected in some cases – locally and for a limited time,” said BfS President Inge Paulini. “However, the recommended maximum values for fields induced in the body were complied with in the scenarios investigated, so that according to current scientific knowledge no health-relevant effects are to be expected.”
The study analysed electric field exposures in different parts of the vehicle during various operating states. It revealed the strongest fields typically occurred near the floor, particularly in the foot area, with significantly lower readings at head and torso level. Driving style had a notable impact on exposure levels, with peak fields emerging briefly during strong acceleration or braking.

Short-lived spikes, lasting less than one second, were recorded during events such as switching on the vehicle or pressing the brake. The highest single reading came during the startup of a hybrid model.
While no correlation was found between vehicle motor power and magnetic field strength, Paulini noted that manufacturers can influence exposure levels. “The manufacturers have it in their hands to reduce local peak values and keep average values low with an intelligent vehicle design,” she said.
The study also examined electric two-wheelers for the first time, including scooters and motorcycles, finding similar results—maximum magnetic field values remained below recommended limits.
Despite the positive findings, the BfS recommended updating measurement regulations to include very short-term field peaks, which are currently excluded. “The investigation showed that they occur to a relevant extent,” the agency stated.
