The electromagnetic pulse is a strategic weapon by stirring up damaging voltages and current. The electric circuits are not durable for an EMP. It is lethal to the electronic devices and the whole system. The chances of damage of the smaller electronic devices are greater than the larger devices. The nuclear EMP artillery explosion at high elevation can expand to various regions. The assault of the electromagnetic pulse can reach up to 1,500 miles and it will be the reason for great destruction. Below is a brief summary of the EMP nature of your understanding:
The sudden burst of the radiations can immediately change the energy level, and the electrical devices, appliances and vehicles will immediately stop working. The non-shielded devices will immediately stop working, and your food and water supply will also stop. It is important to understand the need of water and food supply. You should learn to live without all these facilities, electronic devices and traditional supply of the food and water. You will not be able to use your vehicles because they may stop running. You will be leaving on foot, or other physical vehicles. If your residential area is prone to an EMP attack, then you should learn to survive without all amenities and traditional food supply chain.
