How to Get EMP Protection?
If there’s something that you need to know about the world now, then it is the fact that an electromagnetic pulse or EMP attack is not just a threat but a real possibility. That’s the reason why you should have an EMP protection plan and also, the same reason to why it has been long overdue to have yourself protected from EMP attack.
In this article, we are going to talk more about what EMP does and to how you can get yourself protected from it.
When a conductor moved in a magnetic field, this produces an electrical current. This technology is very useful and is what used for generators to work at local power plants. Similarly, when the moving magnetic field passed through a conductor, it is going to create a current and this is simply known as EMP or Electromagnetic Pulse. It sounds technical and it looks complicated because it is.
What could possibly happen in case that the magnetic field that has been produced is stronger when it passed through the wire? Perhaps, there will be a pulse large enough to damage the wiring and by the term damage, I mean fried from the inside. A pulse that’s so intense may fry out the microscopic wires in small circuitry. In the event that the magnetic field is strong enough, the electrical burst can destroy the microelectronics.
Fortunately, there are a number of ways on how we can protect our devices from an EMP attack. Electrical shielding is among the known techniques for EMP protection. In the event that the electrical cable has grounded shield, the EMP isn’t going to penetrate that shield. It will be inducing current in the shield and harmlessly release that current. This is awesome option for cables but what about the smaller devices like microelectronics?
In this case, you can protect the whole device by making use of a Faraday Cage. This has been named after an early scientist Michael Faraday who discovered the presence of electromagnetic. He had discovered the electromagnetic field is not able to penetrate a container that’s made out of a particular metal. Instead, the field impinges the exterior of the cage and because all sides of the cage are connected electrically, there is no induced electrical current.
Devices that are put inside the cage are protected from damaging current because for a current to flow, there must be a differential electrical potential. If you seek for better EMP protection, there is this called Nested EMP Faraday cages. Simply speaking, this is a cage that is put inside a cage.
