Magnetic fields in electric cars are minimal


Researchers from seven countries have concluded that we can feel safe both in electric-powered cars and in those powered by hydrogen, petrol and diesel. None of them exposes passengers to higher electromagnetic fields than those recommended in international standards. In fact, field intensity is well below the recommended value. The study is currently the most comprehensive ever carried out in this field…

“There is a good deal of public concern about exposure to magnetic fields. The subject crops up regularly in the media. With the number of electric-powered vehicles increasing, this project is very relevant,” says Kari Schjølberg-Henriksen, a physicist at SINTEF…

The intensity of magnetic fields in seven different electric cars, one hydrogen car and one petrol car were measured in order to ascertain whether they approach the recommended limiting values for human exposure. The measurements were carried out using real cars in a laboratory and during road tests.

The highest values in electric cars 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 per cent of the limiting value recommended by the ICNIRP. Measurements taken at head-height are less than 2 per cent of the same limiting value.

In the case of petrol and diesel powered cars, exposure was measured at around 10 per cent of the limiting value. In other words, there is little difference between electric cars and petrol and diesel cars

“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,” Schjølberg-Henriksen points out.

He probably shouldn’t have added that last point. I can see conspiracy nutballs right now preparing talking points aimed at removing wheels from automobiles.

If the travois was good enough for Native Americans, it should be good enough for us.
