Let an agent explain electromagnetic pulse and its natural and artificial sources in general terms, relay effects on infrastructure and protection standards from public sources, present policy debates with attribution, and avoid operational detail on weapons.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain electromagnetic pulse and its natural and artificial sources in general terms, relay effects on infrastructure and protection standards from public sources, present policy debates with attribution, and avoid operational detail on weapons.

A short burst of electromagnetic energy that can disrupt or damage electronic equipment, arising from natural sources such as lightning and the geomagnetic storms driven by coronal mass ejections, or from artificial sources including nuclear detonations at high altitude and specialised devices; electromagnetic pulse is a concern for power grids, communications and satellites, is addressed by shielding and hardening standards, and is the subject of policy debate, while the phrase set and reset pulse names an unrelated circuit signal.

What it is for: Not applicable; a physical phenomenon and hazard.

It can be explain the phenomenon and sources; relay effects and protection; present policy debates; distinguish related terms.

Distinguishing features

Broadband transient

Natural and artificial sources

Infrastructure vulnerability

Hardening standards

What it looks like

Not a visible object; a transient recorded on instruments.

Physical character

nuclear EMP E1 rise time: nanoseconds time - per public standards

Carrington event: 1859 year - largest recorded geomagnetic storm

How it is recognised

Transient electromagnetic burst

Lightning, geomagnetic storms, nuclear EMP, specialised devices

A coronal mass ejection is the solar source, not the pulse itself; set and reset pulses are circuit signals

What the second pass must settle

  • Should geomagnetic storm and nuclear EMP be separate entries?
  • How should protection standards be linked?
  • The registry entry has merged aliases naming a solar source and a circuit signal; should they be split off?
