The Master Of Magnetics "Steven Mark"

I?m sorry if I introduced some confusion about DC components. For a better common understanding, we can consider the following:
- A pulse (every shape) from -2.5 to 2.5 volts, for instance, has not got any DC component (we assume a symmetric shape negative-positive).
- A pulse from 0 to 5 volts has got a DC component
- Both of them have an AC component (the same!!!).
Right? If right, we understand the same.
Then:
-I think, every DC component doesn?t generate anything in a coil. All emf?s or something like that are generated by AC components (consider the above example, both can ?generated? the same). If there are other cases I am very interesting to know it.
-The signal present in a coil as result of a generated (or transformed) energy will be AC pure signal if the process is reversible (because if a reversible process exists there are two possible outputs with the same input, that is not possible).
I think if DC components are observed, the energy generation process can?t be a reversible process. Then emf?s and analogues process can?t be applied.
Probably we are talking about discontinuities were usual models are not applied (as Kames explained with di/dt). Spark gaps are discontinuities, for example. Some of them are irreversible processes.

Hi everybody,

Took me almost a day to find one article, but finally have found. Will definitely save it on my disk that next time I don?t have to search for it again. Have a look at the next link:
http://www.allaboutcircuits.com/vol_2/chpt_9/12.html
Most of the stuff is well know, but search for the next text: ??.A significant difference exists, however, between continuous-mode operation and the sudden starting condition assumed?..?. Think about a short impulse traveling ?ALONE? or a ?kick? and read to the end.

Regards.

Very interesting article, Kames, thanks.
You can find another in the same web (the back page, http://www.allaboutcircuits.com/vol_2/chpt_9/11.html ). The first figure is the fundamental idea of magnetic amplifiers. Mix this (amplifier) with soliton concepts and maybe we have a interesting material for studying.

Why should the magnetic shield used in color picture tube?

ELF and VLF radiation from deflection yoke

- MPRII
Swedish Low Radiation Standard. Monitors generate both VLF (Very Low Frequencies 0.1KHz to 400 KHz) and ELF (Extremely Low Frequencies 1 Hz - 1000 Hz ) frequencies. These EM fields are generated by the monitor's deflection yoke which positions the electron beams. The horizontal refresh rate generates frequencies in the VLF range, and the vertical refresh rate generates frequencies in the ELF range.
The Swedish National Board of Measurement and Testing developed a set of standards for measuring, and came up with acceptable levels for electro-static potential , alternating electric and magnetic fields.
Hansol monitors limit build-up of electro-static by using an Anti-Static conductive silica coating on the face of the CRT. Emission cancellation coils mounted on the deflection yoke are also used to significantly limit both the VLF and ELF electromagnetic fields.
MPRI Standards created by the Swedish Labor Unions 1986. First version of MPRII. MPRI only addresses VLF 0.1 KHz to 400 KHz.
MPRII Standard created by the Swedish Labor Unions 1987. This defines the level of acceptable emissions ELF, VLF, electric, magnetic and static discharge from monitors.
VLF = Very Low Frequencies 0.1KHz - 400 KHz
ELF - Extremely Low Frequencies 1 Hz - 1000 Hz
MPRII Limits
Electro Static Potential Within + or - 500 volts
Magnetic Field
Band I 2 to 400 KHz < or = to 25 nt
Band II 5 Hz - 2 KHz < or = to 250 nt
Alternating Electric Field
Band I 2 to 400 KHz < or = to 2.5 v/m
Band II 5 Hz - 2 KHz < or = to 25 v/m

Kick start

Another suspicious circuit element in colour monitors is the degaussing circuit (refer Fig. 13). It acts only when the monitor is switched on and lasts only for a few seconds.

The red, green, and blue electron beams are always critically aligned to the corresponding phosphor dots on the face plate. However, local magnetic perturbations can misalign the whole set-up, giving rise to localised colours. Therefore it is necessary to ensure that the shadow mask and the other metal parts inside the CRT are completely demagnetised before the monitor is to be used. The process of demagnetisation is called degaussing.

The degaussing circuit sends AC current through the coil wound around the face of the CRT, generating a gradually diminishing AC magnetic field or H field. A typical degaussing circuit may have a peak-to-peak current of 4.5 to 6 amperes when switched on, and below 2 mA after 30 seconds. It does not perform a little extra job of demagnetising things in the nearby areas including the user.

The applied H field is always directed towards the face of the CRT and operates straight from 220V AC line. So in many establishments, expectant mothers are advised to keep away from colour monitors. It is alleged that while the colour monitor wakes up with a big yawn, the sleeping fetus may be tickled mercilessly.

Hi everybody,

Here are my final thoughts about Steven?s device and over unity in general. If there is more, I don?t mind to change my mind, but no promises to answer all of the questions or objections -:), just don?t have time for everything and don?t like promises, especially in the field of free energy. After this post I am going to recover my old experiment that I mentioned before.

In my opinion, there are two major conditions that make the device to be self-running. The first is known to everybody and the second (which I have never mentioned)?., I hope you are not going to start throwing tomatoes at me -:).

1)It is obvious that the main condition is to have something that provides excess of power. In case of Steven? device it is a ?kick?. We can describe the effect as an effect of the earth magnetic field or we can describe it on the paper. Whatever way is easier to explain it for somebody is the best way to go. For me it was a combination of different ways, a little of nature, a little of mathematic and a little of theory. In the reference to the article that I have posted before ( http://www.allaboutcircuits.com/vol_2/chpt_9/12.html ) the very last picture shows a change of the current that is at least at the first part (especially if you make an impulse shorter) of it can be described as a function ?k + x^2?. That is why I have said that a more correct way to describe the effect would be ?lim (di/dt)? instead of just ?di/dt?. You can also recall a very famous article ?Nothing is something?, which is not directly related but you might like to search for ??..Electrometer readings were always close to parabolic, thus indicating that the source was of infinite capacity?..?.
By the way, would Steven?s device work out of space?
2)And here is the second condition, where I probably should cover my head, just in case -:). You would be really surprised if I say that even the excess of power is not enough to make the device to be self-running. You need the device to be ABLE to transfer more energy from input to output, or you can say you need unequal behavior between input and output (do not look only at coils even if the coils are all you have). You can use my example with a simple transformer with the time splitting, or Sweet Floyd device with standard and bifilar coils, or a transformer from a standard computer switching power supply, or Steven?s device with the output frequency greater than the base input shown as a vibration and/or gyroscopic effect. Obviously, there are much more examples but it is not that simple in every case to determine what can possibly constitute it. ?Most? of the time the ability of the device to be self-running is determined by the ratio ?output/input?. But let me ask you a question, if both arguments go to infinity, what would be the result? That is where a more correct way would be to say ?lim (output/input) with load -> to infinity?. In other words, you have to determine which part is going to infinity FASTER.

That is it.

Regards.
