A magnet, a conventional explosive, and a coil on a flexible cylinder of polymer film; are power electronics truly necessary for a localized EMP?

I'll bet you could make it in a weekend.

Only if one understands the different failure modes, but either way the average HN reader shouldn't try this at home or you'll get in trouble with radio spectrum pollution.

Yes. Range, accuracy, targeting, and reducing blast radius matter.

Not sure what else I can say so I'll leave it at that, and will not engage with further comments.
