Electric vehicles convert high-voltage DC battery power to AC for their motors, generating significant magnetic field exposure.

“I think the biggest detriment of cars both IC and electric vehicles is the magnetic field component and a big problem in general in terms of like dirty EMF or like high EMF things is when you're converting power whether it's DC to DC AC to DC or DC to AC um because you're using a lot of rectification and it's resulting in a lot of emfs so electric vehicle has these you know 400 800 volt batteries they're DC and then they have to convert that at very high power to run their AC induction motor”
