I have no record in electrical engineering; this is a total outsider question which might be grasped absurd.
Wikipedia defines [EMP](https://en.wikipedia.org/wiki/Electromagnetic_pulse) as:
> An electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse's origin may be a natural occurrence or human-made and can occur as a radiated, electric, or magnetic field or a conducted electric current, depending on the source.
