when they say things like a nuclear bomb could cause a blackout, what happens to the electricity? how does it work?

A nuclear explosion causes a pulse of electromagnetic radiation. This pulse is a rapidly changing electrical field and rapidly changing magnetic field.

These would couple/induce rapidly changing currents/voltages in electrical/electronic devices and these could be enough to damage/disable those devices.
