OT: EMP and Equipment

Yes.

>The reason for the terse questions is your asking a broad >question. Basically EMP is a sudden expansion then contraction >of a magnetic field. From basic electronics there are two ways >to generate power using magnets (or their fields) one is to move >the wire and the other is to move the magnet. > >The amount of energy induced into a wire is dependent on how many >lines of force you traverse and thats related to how strong the >magnets field is (also how close). > >We get EMP from two sources, one common. The nuke version can >be very strong but if your close enough for EMP then you may be >too close to worry. The other common source is lightinging, every >bolt we see represents a momentary huge current that collapses >very quckly with the attendent magnetic fields. There are two >protection methods applied for lightining. One being electrostatic >and the other recognizes the electromagnetic. Protection for the >latter is simple most of the time. Disconnect the power cord, >antennas, and any control lines. In short remove any "wires" that >can have an induced field and transfer that voltage inside to the >sensitive parts. Ideally for complete protection a iron or steel >case with no breaks is best protection against near misses. In >both cases distance fromthe event is a really good thing as >magnetic fields are squarelaw IE: at twice the distance it's >one quarter strength. > >So yes you can protect your hardware, assuming your far enough >away to survive. You still ahve to worry about high energy >particles (neutrons, beta and gamma particles) and other >radiations ( Xrays and infared). > >
