Electricity operated devices such as electronics can be destroyed when an electromagnetic pulse of great magnitude occurs. Civilization as we know it now can be crippled by an electromagnetic pulse if it hits at great magnitudes. The sun emits energy constantly and if the energy crosses paths with the earth as it revolves, it can cause an electromagnetic pulse. Upon explosion of a nuclear weapon, energy waves are transmitted which contain the electromagnetic pulses. It is possible for these energy blasts to be directed to specific regions by opponents especially in times of war between nations.
When this happens, it can lead to a lot of damage to electronics and lead to panicking of people all over. If the pulse happens and a device is connected to electricity, it would automatically get fried since the power is too much for the devices. Such places as cities would be full of chaos when the energy burst brings down power creating a blackout in such places. It is always better to survive an emergency by being prepared before it happens and since these blasts are unpredictable one should be ready at all times. Electronics such as computers, generators and solar panels should be protected in case of the pulses. There are certain bags designed to give protection against these energy waves by restricting waves from entering or leaving the bags.
Laptops, phones or any other device can have a bag customized to fit it so as to protect them from these energy blasts. The bags were invented by Faraday who carried out tests on how to block electromagnetic waves. Most of the electronics are expensive which makes it cheaper to buy the bags for them instead of being forced to buy new ones when they get destroyed by the pulses. It is good to cover phones using the bags to protect oneself from the pulses being constantly emitted by the phones. Since laptops and phones give out some signals these could be used by malicious people to gain access and steal or destroy data.
Such threats can be avoided when carrying the devices inside the bags because the signals can not get out or inside the bags. Things like credit card information and other confidential data is secured while outside using the bags as a shield from those malicious people. By covering such utilities as generators and solar panels with such protective bags, one avoids chances of blackouts during such events as energy blasts. An occurrence of such pulses can cause a lot of damage to extensive areas and make communication and other things depending on power to fail.
