Creating an electromagnetic pulse (EMP) without using nuclear weapons or electricity is extremely challenging and currently not feasible with existing technology. EMPs are typically generated by the rapid release of a large amount of energy, which can disrupt or damage electronic systems.
The most commonly known method of generating EMPs is through a nuclear explosion, where the detonation produces intense gamma radiation that interacts with the Earth's atmosphere, creating the EMP effect. This method is highly destructive and not something that can be easily replicated without a nuclear weapon.
Another way to generate an EMP is by using powerful electromagnetic sources such as specialized generators or devices known as Marx generators, which produce high-voltage pulses. However, these devices require a substantial amount of electricity to function properly.
Currently, there are no known methods to generate an EMP without electricity or nuclear weapons that would have a significant impact on electronic systems. EMPs are complex phenomena that require specific conditions and substantial energy to produce the desired effects.
