Not that we ever believed that electromagnetic fields were a safety problem associated with electric vehicles, but it's still comforting to have a full-blown study prove that electromagnetic fields aren't an issue to be concerned with in regards to EVs.

As Green Car Congress writes:

"The EU-funded study EM Safety, led by SINTEF, has found that neither electric-powered cars—nor those powered by hydrogen or gasoline—expose passengers to higher electromagnetic fields than those recommended in international standards. Field intensity is actually well below the recommended value. The study, involving SINTEF and nine other European companies and research institutes, is currently the most comprehensive ever carried out in this field."

In brief, the results of the study show that:

"The highest values in 7 electric cars under test were measured near the floor, close to the battery itself and when starting the cars. In all cases, exposure to magnetic fields is lower than 20% of the limiting value recommended by the ICNIRP.  Measurements taken at head-height are less than 2% of the same limiting value."

"In the case of gasoline and diesel powered cars, exposure was measured at around 10% of the limiting value."

All of the tested vehicles fall below defined limiting values of acceptable exposure to magnetic fields, as laid out by The International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Kari Schjølberg-Henriksen, a physicist at SINTEF, concludes the following:

"There is absolutely no cause for concern. The difference between this research and similar earlier work is that we have taken into account what contributes to the magnetic fields. The rotation of the wheels themselves generates considerable magnetic fields, irrespective of vehicle type."

So, it seems you should be more concerned by the magnetic fields created by rotating wheels then by the magnetic fields that electric vehicle specific components may generate.
