Magnetic Fields Inside EVs: What the Measurements Show and Where They Come From

Hand-drawn sketch on squared paper: a wide current loop producing a large field, a paired DC plus and DC minus conductor pair whose fields cancel, and a bar chart of measured front-seat magnetic flux density in microtesla for two electric cars at steady speed and under acceleration.

Do electric vehicles expose their occupants to electromagnetic fields? Yes, to low-frequency magnetic fields, and the published measurements put most readings below the public reference levels, with a few that need a closer look. This post sets out what the measurements show, then treats it as a design topic: the field comes from current loops … Read more
