While I think the legality for such a device is a gray area one strong enough to damage or stop a car could kill or injure anyone around with a cardiac device or other electronic medical equipment.

My understanding is that EMPs are more of a concern for the tiny electronics on computers versus relatively large motors or batteries. So, an electric vehicle is still at risk, but I don’t think it’d be any more at risk than any ICE car that’s all computerized anyways.
Nuke type EMPs are a threat to very long wires, like miles long ones used to transmit power. The blast causes a ripple in the earths magnetic field that induces current over huge distances. But I don’t know what a more handheld device would affect.
Electric motors work by inducing a magnetic field with coils of wire, so I’m sure a strong enough EMP would disrupt it temporarily, but I don’t know if it would meaningfully damage anything after the EMP ceased.
They’re made specifically to deal with high electromagnetic flux, so it definitely wouldn’t hurt them long term. Best bet would be something higher frequency to mess with the computers.
I’m curious if anyone knows if cars, especially electric cars, are vulnerable to EMPs?
just interference, but you need a nuke to initiate an EMP effectively. i think some ev cars were susceptible to other forms of interference.

Build one and report back. 🤷
Hmmm. Well, I do love taking apart old microwaves…

It would probably mess up the controlling computer though.
Occasionally cars get hit by lightning and that usually causes a lot of errors and glitches and sometimes it totally writes off the vehicle.

Got it, so it’s best to use a nuke just to be safe.
