This is usually accomplished with a explosive lense plane wave generator which produces a uniform plane wave burn (or detonation) front in the explosive.
In an explosive or propellant driven MHD device, the conductor is a plasma of ionised explosive or propellant gas, which travels through the magnetic field.
The electrical properties of the plasma are optimised by seeding the explosive or propellant with with suitable additives, which ionise during the burn.

  Explosively pumped flux compression generator
An explosively pumped flux compression generator (EPFCG) is a pulsed power supply that magnetically derives its energy from an explosion.
EPFCGs are popular as power sources for electronic warfare devices known as transient electromagnetic devices that generate an electromagnetic pulse without the costs and side effects of a nuclear weapon, a form of cyberwar.
An EPFCG package that could be easily carried by a person can produce pulses in the millions of amperes - tens of terawatts[?], excedding the power of a lightning strike by orders of magnitude.

Compression is useful because it helps reduce the consumption of expensive resources, such as hard disk space or transmission bandwidth.
For instance, a compression scheme for video may require expensive hardware for the video to be decompressed fast enough to be viewed as it's being decompressed (you always have the option of decompressing the video in full before you watch it, but this is inconvenient and requires storage space to put the uncompressed video).
Compression of human speech is often performed with even more specialized techniques, so that "speech compression" or "voice coding" is sometimes distinguished as a separate discipline than "audio compression".

It is not known for certain, though it is suspected, that at very short range the pulse may severely injure or even kill humans due to RF heating effects in the body.
In any case, this would require a person to be at such proximity to the device that they would stand a far greater chance of harm from the shockwave from the explosive and the high-speed shrapnel from the bomb casing.
It is suspected that some of the current research in FCGs is focused on replacing the conventional conducting metals in the device with superconductors, thus allowing phenomenally higher currents and magnetic fields to be achieved at detonation.

 EMP - Battlestar Wiki
Just before the Cylon attack, "electric pulse generators" are being transported to Caprica from the decommissioned battlestar Galactica on Colonial Heavy 798, presumably to place in a planet side museum or school as a historical artifact, or for re-use on another ship (Miniseries).
It is also probable that such devices were part of a battlestar's fighting tactics against Cylon attacks, since (at least in the first Cylon War, although not in the second), Cylons were purely mechanical and thus vulnerable to EMP attacks unless shielded.
The gamma radiation generated by an explosion alone can nonetheless disrupt DRADIS and wireless communications, as they rely on a form of EM radiation as well.

These include electromagnetic forming, Marx generators, pulsed lasers (especially TEA lasers), pulse forming networks, radar, fusion research, and particle accelerators.
Dielectric or metal interconnection failures may create arcing within oil-filled units that vaporizes dielectric fluid, resulting in case bulging, rupture, or even an explosion that disperses flammable oil, starts fires, and damages nearby equipment.
Rigid cased cylindrical glass or plastic cases are more prone to explosive rupture than rectangular cases due to an inability to easily expand under pressure.

This typically involves converting 120 or 240 volt AC supplied by a utility company (see electricity generation) to a well-regulated lower voltage DC for electronic devices.
In the simplest case a single diode is connected directly to the mains and uses a resistor in series with a more or less fixed load to recharge a battery.
A more accurate term for devices that convert one form of electric power into another form (such as transformers and linear regulators) is power converter.
