[[Image:Flux compression generator 1.png|thumb|upright=1.2|A hollow tube type of explosively pumped flux compression generator. The hollow copper tube acts like a single-turn secondary winding of a transformer; when the pulse of current from the capacitor in the windings creates a pulse of magnetic field, this creates a strong circumferential current in the tube, trapping the magnetic [[field line]]s within. The explosives then collapse the tube, reducing its diameter, and the field lines are forced closer together, increasing the field.]]

The [[Implosion (mechanical process)|implosion]] compresses the magnetic field to values of around 1,000&nbsp;T<ref name="MagnetLabU" /> for a few microseconds. While this method may seem very destructive, [[Shaped charge|shaped charges]] redirect the blast outward to minimize harm to the experiment. These devices are known as ''destructive pulsed electromagnets''.<ref name="MagnetLab-pulsed">{{cite web
