An EMP (electromagnetic pulse) can be created by space weather, like massive solar flares, as well as HEMP weapons. In a nuclear war it is possible that the first nukes used would be HEMP weapons in an attempt to knock out defenses. As the EMP hits the faraday cage, the energy travels around the outer metal material but not through the insulator. Batteries should not be effected by an EMP but might be useful stored with your electronics for easy access. If you have certain individual electronics you use regularly and want to add a level of protection, consider buying small faraday bags.

Please note that all modern Lithium Ion batteries have management electronics built in, and thus be vulnerable to an EMP.

A Faraday cage will protect sensitive electronic devices from an EMP (electro-magnetic pulse). Given how cheap and easy it is to construct a Faraday cage, this is something that all preppers should consider doing, so they can protect vital electronic devices in the event of an EMP.
High Altitude Electromagnetic Weapons (HEMP weapons) are nuclear weapons that are detonated high in the atmosphere.
If they are not protected in a Faraday cage, most electronic devices will be not work after an EMP.


You might have the materials lying around in your garage right now – and if not the cost to build one is very low and can sometimes be done in less than 10 minutes.
If the box is grounded to the earth (third prong in household wiring or to a metal rod stuck in the ground) it should work better, but this is not required.
The reader should seek his or her own legal or financial advice from a qualified professional. Electromagnetic pulses don’t hurt people directly, they just wipe out communications and infrastructure.
