1) Electromagnetic warfare is a growing concern and threatens developed countries by interfering with electronics like mobile phones, laptops, and power grids. 2) Electromagnetic waves carry energy, momentum, and angular momentum and can interact with charged particles. They are produced when charged particles are accelerated. 3) Weapons that use electromagnetic pulses (EMPs), such as E-bombs, can potentially paralyze communication systems and damage electronics over large areas. EMP weapons work by using devices like flux compression generators to produce powerful electromagnetic pulses.
