Explosions of high yield bombs in the ionosphere above the target. The effects can reach for a radius of a couple thousand miles around ground zero.
electromagnetic pulse is one of the effects caused by
nuclear
Nuclear
An electromagnetic pulse (EMP) is typically associated with a high-altitude nuclear explosion or a cyberattack targeting critical infrastructure systems. The EMP can disrupt electronic devices and infrastructure by generating a strong electromagnetic field.
High altitude burst inside the ionosphere.
Nuclear attack
Nuclear
No!!
EMP is only a significant effect if the bomb is detonated in the ionosphere.
A nuclear attack. EMP is generated by the energy of electrons added to the Earth's magnetic field by gamma radiation.
Nuclear
The explosion of an atomic weapon can cause an EMP.
