EMP pulse...

Have you heard of electromagnetic pulse? Supposedly,
a big nuke exploded over Colorado will erase every magnetic
memory west of the Mississippi. (not sure about semiconductor memories)

Can anybody here explain the physics of this claim?

Nukes can make giant EMP pulses. One high atmospheric test crashed
Hawaii.

There are also non-nuke EMP weapons, like jet planes tiled with pulse
emitters, or rockets with explosive-powered EMP generators.

google HPM weapons

Might be a defense against cheap drones.

The physics behind the \"explosively-pumped flux compression generator\"
is pretty simple conceptually, you have a solenoid wrapped in high
explosive. Dump a capacitor bank into it to get a large current moving,
then detonate the explosives and symmetrically crush it, inwards towards
the longitudinal axis of the solenoid.

Lenz\'s law does the rest.

The planes have tiles that are antennas, basically a charged capacitor
with some shorting device, possibly a poly-diamond film.

Seems more amenable to a longer duration effect than the former. Quieter
too, I bet the EPFCG makes an awful racket, to put it mildly

The discharge tiles make one giant spike at low rep rate. Presumably
one terawatt impulse can blow out sensors or trash the CPU in an
incoming threat. Of course, the launching airplane has to survive it
too.
