MEG

[wings]

seems that even the MEG works with coil shorted http://www.hyiq.org/

This is of great significance !!!!!

"On rare occasions, Sweet saw this effect, called self-oscillation, occur in electric transformers"

and

"Sweet was also a transformer designer and expert, and he remarked that he had also observed specialized self-oscillation in certain transformers. "

See: http://www.hyiq.org/Library/18-07-11.htm

I show the importance of knowing and understanding the A Vector Potential and how simple it is to create a self assisted oscillation. This set of shorted Self Assisted Oscillating Coils. This can be improved hugely and is possible to be made to self run with this technology. Nikola Tesla, Floyd Sweet, Lester Hendershot, Edd Leedskalnin and Daniel McFarland Cook all knew about this technology. They all used it in various ways to improve their devices...."

Has anyone tried reproducing any of these MEG's?  From what I understand, the speed the coils can switch on/off is the biggest bottleneck.

An open source MEG design would do wonders for the OU development community.

Hi joenobody,

I made several attempts to replicate MEG. But no luck so far.

If this is the identical person it would be a good scientifical background

With such a tool less speculation:


4:30 [/size]New Metallic Contaminant Detection System Based on Faraday's Law of Electromagnetic Induction[/size][/color]Saburo Tanaka, PhD, Prof, National University Corporation, Toyohashi University of Technology, JapanFor manufacturers producing Li-ion batteries or its materials, problems with metallic contaminants are critical issues. When contamination occurs, the manufacturer of the product suffers a great loss from recalling the tainted product. The lower detection limit for practical X-ray imaging is on the order of 1 mm. A detection system using a SQUID is a powerful tool for sensitive inspections. We previously proposed a direct detection system using multi-channel SQUIDs. In that system, an object with a contaminant is magnetized by a permanent magnet, and then a SQUID detects the remnant field of the contaminant. Because the detection width is defined by the size of the SQUID, eight-channel SQUIDs are required to inspect a specimen with a width of 65 mm, for example. This procedure is costly, and as a result, the system has not been widely used in the field. To circumvent this problem, we propose an indirect high-Tc SQUID magnetic metallic contaminant detector combined with a coil and magnet. The principle of the system is based on Faraday's law of electromagnetic induction. The detection section consists of permanent magnets and copper-wound pickup coils. The signal is magnetically transferred to a SQUID magnetometer. The differential pickup coil successfully measures an iron test piece with a size of 40 µm when the test piece was moved with a speed of 100 m/min. The advantage of this indirect detection method is that the detection width is wider than the previous SQUID direct detection method. The detector is able to detect a 50-µm iron test piece within a range of 20 mm with an SNR greater than 5. Since two coils are differentially connected in series, a detection width of 40 mm (2 - 20 mm) per channel is realized and two SQUIDs are sufficient for an inspection width of 65 mm. This is a great advantage compared to the direct detection system, which requires eight-channel SQUIDs to inspect an object with a width of 65 mm. This detection method is effective for the inspection of non-metallic materials such as the plastic film separator of a Li-ion battery. If the criterion of the detection size is moderated and 100 um, the SQUID sensor can be replaced by a low cost flux gate magnetic sensor. In the case, the cost of the system is dramatically reduced. In my talk, the evaluation results of the indirect contaminant detection system using a flux gate magnetic sensor will be also discussed.
