I gag when I read an apocalyptic EMP novel. I was working on my PhD thesis of laser holography. Projecting an electromagnetic field. Back when Oog dragged Ooga off by the hair (1971).
May I present to you a raw and crude model or example for your analysis?
Inside an alternator the rotating part called a (rotor) projects a variable frequency field. Variable by polarity and variable by frequency. Both types of frequencies
Analog
PWM pulse width modulation
Modern alternator voltage regulators utilize transistors. Field Effect, MOSFET and earlier designs. It gets worse. Many voltage regulators directly source the vehicle engine management control unit the ECU.
And this sensitive pressure point is mounted in a plastic shell a scant inch distant from electromagnetic pulses that are perhaps as much as 1.6x10 as intense as the characteristic model of an EMP detonation or even coronal mass ejection even of the sun.
How is this possible?
It is because these circuits (meaning automobiles) lack an inductive pickup area that can accumulate enough EMF to saturate an electronic circuit to the point of destruction or damage. An antenna is needed and it has to be of extraordinary db gain.
Fantasy
The metal shell of an automobile is an extremely effective faraday cage.
The detonation of an EMP producing high altitude H-Bomb in the Pacific Ocean gained much attention when street lamps in the Hawaiian Island reportedly failed. The press went hog wild. Yet later analysis of maintenance records showed without a doubt there had been periods where even MORE streetlamps had failed over a 24 hour period.
Let's go back to those pulp EMP novellas. In many cases the only surviving method of communications was amateur radio operators and their tall antennas feeding high gain amplifiers. Fascinating.
The only commonly found circuits vulnerable to EMP induction have high gain antennas. Like HAM radios, hundreds of thousands of miles of distribution and transmission electrical networks with transformers. Yet a bolt of lightning can strike a network and devices like reclosers protect your home (neighborhood networks do not have reclosers nor do they have enough gain to induct critical levels of electromagnetic force from a pulse.
A magnetic resonance imaging machine develops thousands of times more electromagnetic force than a so-called back to the stone age mass coronal ejection. For a trick I hid a plastic case Velcro strap watch in a waste can, my second MRI. The same class of General Electric MRI machine that killed a janitor in Brazil this month when he entered a room with an energized MRI. It pulled on a steel case of a 10 lb fire extinguisher dragged him 15 feet across the floor and slammed against the magnetic coil housing. When the contents of the extinguisher evacuated he was suffocated.
When I was ejected out of the machine, before I was seated in a wheel chair, I fetched my still running digital watch. The nurse gave me a dose of aggravated RN which lasted all the way to my novel.
There are two main intertie grids in the USA, the Quebec and the Western. The western has seen numerous upgrades the Eastern grid is anyone's guess.
CME or thermonuclear detonation grid damage? Yes. Back to the stone age....hardly. Freeways clogged with dead automobiles....in your dreams....there would be some failures due to Bluetooth type integration. Amateur Radios broadcasting in the vacuum? I have to quit...my ribs ache. Where the hell is my Nook...they were just entering a dead city when a gang of motorcycle anarchists...
