A type of explosive generator
that relies on the principle of conservation of flux
. Roughly, the device consists of a solenoid
, a capacitor
or other method to energize the solenoid
, and explosive charges
to compress the solenoid
In operation, the solenoid is energized, creating a magnetic field running through it. The explosive are then detonated, compressing the solenoid. Since the total magnetic flux through the solenoid tends to be conserved, this causes an enormous current to form in the solenoid. Typically, they generate currents on order of 60 times the initial current for a few milliseconds.
Flux compression generators can be staged, with each one energizing the next stage. This is useful where truly massive currents are required, such as an EMP bomb.
