The effect of a Nuclear Blast on Planetary Magnetism

[Socrates271]

Has anyone ever come across any research or articles concerning the effects of the initial blast and fallout of an nuclear weapon and its effects on surrounding magnetism?

Theories are welcome too, but research is preferred.

Welcome to PF, Socrates. I have not seen any such research, but I'd imagine that a nuclear blast couldn't do much permanent damage to the magnetosphere, considering it is the result of the dynamo effect that takes place in the safety of the Earth's outer core (about as good a bomb shelter you can get). That's not to say it couldn't affect it at all, though. Large bursts of energy (solar flares, etc.) are very capable of "denting" our magnetic field.
