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. This is actually one of the reasons why you should prepare an EMP protection plan and the same reason too why it’s been long overdue to protect yourself from EMP attack.

By reading this article, you are going to learn how you can protect yourself from EMP and at the same time, to what it really does.

When a conductor moved in a magnetic field, this produces an electrical current. This sort of technology is widely used today, more so to operate generators at local power plants. Similarly, when the moving magnetic field has passed a conductor, it is creating a current and this phenomenon is otherwise referred to as EMP or Electromagnetic Pulse. This sounds to be technical and complicated as well, because it really does.

What would happen in case that the magnetic field 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. With magnetic field that’s so strong, the microelectronics may be destroyed by the electrical burst.

But don’t worry, you can actually do something to protect your devices from possible EMP attack. One of the commonly used techniques to get protection from EMP is electrical shielding. In case that electrical cable has grounded shield, the EMP won’t be able to penetrate that shield. It is going to induce current in that shield and harmlessly release that current. This is awesome option for cables but what about the smaller devices like microelectronics?

Well there’s a simple resolution to this one and it is by simply putting the whole device inside a Faraday Cage. This is actually named after Michael Faraday who is an early scientist who has learnt about the presence of electromagnetic. According to his discovery, he learnt that by using a particular type of metal, electromagnetic field will not be able to penetrate it. Rather, the field is impinging the cage’s exterior and because all sides of the cage are electrically connected, there isn’t induced electrical current.

In order for a current to flow, there needs to be a differential electrical potential and devices that are held inside this cage are safeguarded from damaging current. Again, there is a device referred to as Nested EMP Faraday cages that is a lot better for EMP protection. Simply speaking, this is a cage that is put inside a cage.
