Try not to confuse nuclear generated EMP (electro magnetic pulse) with EMF (electro magnetic force)
EMP is designed to not due much physical damage but rather confuse electric/electronic systems. Other than a flash of light you might not know it happened until your toaster quits.
EMF is usually very low power level, at near microwave frequencies, and you wont know there’s a problem until your brain tumor gets big enough to bother-—if you don’t keep your 5G phone away from your skull.
I had originally asked the question about the effects of an EMP; I was honestly wondering if there was an effect at all. This stuff is over my head, and it shows🙂
