By adding together the external magnetic field and the induced field, it can be shown that the net result is that the magnetic field lines originally threading the hole stay inside the hole, thus flux is conserved, and a current has been created in the conductive ring. They are being investigated as power sources for electronic warfare devices known as transient electromagnetic devices that generate an electromagnetic pulse without the costs, side effects, or enormous range of a nuclear electromagnetic pulse device.

The variation of the magnetic flux induces a current generarors arrows in the ring by Faraday’s law of inductionwhich in turn creates a new magnetic field circling the wire green arrows by Magnetocumulatjve circuital law.

Magneto-explosive generators use a technique called “magnetic flux compression”, described in detail below. International Journal of Quantum Chemistry.

The new magnetic field opposes the field outside the ring but adds to the field inside, so that the total flux in the interior of the ring is maintained: The technique is magetocumulative possible generaators the time scales over which the device operates are sufficiently brief that resistive current loss is negligible, and the magnetic flux through any surface surrounded by a conductor copper wire, generatoors example remains constant, even though the size and shape of the surface may change.

The most intuitive explanation of this conservation of enclosed flux follows from Lenz’s lawwhich says that any change in the flux genertaors an electric circuit will cause a current in the circuit which will oppose the change. Suppose the ring is deformed, reducing its cross-sectional area.

The nine field lines represent the magnetic flux threading the ring. Chvileva undertook the first experiment with this type of generator, with the goal of obtaining a very high magnetic field.

Such generators can, if necessary, be utilised independently, or even magnetocumulativd in a chain of successive stages: For this reason, reducing the area of the surface enclosed by a closed loop conductor with a magnetic field passing through it, which would reduce the magnetic flux, results in the induction of current in the electrical conductor, which tends to keep the enclosed flux at its original value.

The practical realization of magnetocumulaitve performance MK-2 systems required the pursuit magnetocumlative fundamental studies by a large team of researchers; this was effectively achieved byfollowing the production of the first MK-2 generator inand the achievement of currents over megaamperes from In magneto-explosive generators, the reduction in area is accomplished by detonating explosives packed around a conductive tube or disk, so the resulting implosion compresses the tube or disk.

The first magneto-explosive generators, which followed from the ideas of Andrei Sakharovwere designed to fill this role. An EPFCG package that could be easily carried by a person can produce pulses in the millions of amperes and tens of terawatts.

The magnetic field lines are “pinched” closer together, so the average magnetic field generafors inside the ring increases by the ratio of the original area to the final area. Explosively pumped flux compression generators are used to generaors ultrahigh magnetic fields in physics and materials science research [1] and extremely intense pulses of electric current for pulsed power applications.

Retrieved from ” https: This flux conservation can be demonstrated from Maxwell’s equations. The magnetic flux threading the ring, represented by five field magnetkcumulative, is reduced by the same ratio as the area of the ring. The purpose of the flux generator can be either the generation of an extremely strong magnetic field pulse, or an extremely strong electric magnetocumultaive pulse; in the latter case the closed conductor is attached to an external electric circuit.

Maxwell; Goforth, James; Ekdahl, Carl The compression process partially transforms the chemical energy of the explosives into genrators energy of an intense magnetic field surrounded by a correspondingly large electric current. They are frequently used as the first stage of a multi-stage generator, with the exit current used to generate a very intense magnetic field in a second generator.

Helical generators were principally conceived to deliver an intense current to a load situated at a magnetoucmulative distance.

At the start of the s, the need for very short and powerful electrical pulses became evident to Soviet scientists conducting nuclear fusion research. By using this mqgnetocumulative, you agree to the Terms of Use and Privacy Policy.

An external magnetic field blue lines threads a closed ring made of a perfect conductor with zero resistance. In the spring ofR.

Los Alamos Science An explosively pumped flux compression generator EPFCG is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosive. The simple basic principle of flux compression can be applied in a variety of different ways. The Marx magnetocumulahivewhich stores energy in capacitors, was the only device capable at the time of producing such high power magnetocumultive.
