The Master Of Magnetics "Steven Mark"

Hi Dave,

Just reading the operation of loop antennas again:-

http://www.arar93.dsl.pipex.com/mds975/Content/aerials1.html
From Url:- Ive just taken bits and pieces:-

A Loop or Frame aerial is a wonderful tool to assist longwave and mediumwave reception....
....not only will it dramatically 'boost' the signal received compared to using a portable radio's internal ferrite rod aerial ........
..... the loop will tune very sharply to the required frequency will rejecting all others........
.... The bigger the area of the loop the more signal it will collect.....
.....The radio is simply placed in the middle of the loop and the signals collected are transferred to the radio via its internal ferrite rod aerial.........

END

Now this last point gets me really thinking about the function of the magnets.

I read your post again, but you've eluded me abit, anyway I just thought id post  to help.
I'll have to read your post again, so to understand it better.

I'm really just going by SM's first video, its possible it could be one frequency that he is playing with, until i build the loops and stuff I wont know, but its promising.

Either way, we have some work ahead and I think we are doing quite well.

Sincerely,

Dom

Dave, I forgot to mention from the loop url, this very important point:-

....The circuit for a loop aerial could not be simpler, being a spiral loop consitsting of 10 turns* of 7/0.2mm 'hook-up' wire wound on the 40cm former, and a tuning capacitor to resonate the loop aerial at different frequencies. .....

Resonate, I think this is the key, like the tuning fork:-

My Understanding:-
http://www.physicsclassroom.com/Class/sound/u11l4b.html

The energy carried by this sound wave through the air is tuned  to the frequency of the second tuning fork. Since the incoming sound waves share the same natural frequency as the second tuning fork, the tuning fork easily begins vibrating at its natural frequency. This is an example of resonance - when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion.

The result of resonance is always a large vibration. Regardless of the vibrating system, if resonance occurs, a large vibration results. This was demonstrated in class with an odd-looking mechanical system ....


Sincerely

Hi Dave,

The first video with one magnet, one that starts with chair:-  http://video.google.com.au/videoplay?docid=-8435800732540412467&q=steven+marks

Just reading your post again, correct me if im wrong, the loop antennas, 1 is tuned to say 5000hz and the other loop antenna
is tuned to say 5000.0078 hz   when the two are put together we get the 7.8, which then resonates at that freq, this inturn is induced into the 4 coils within the ring, causing rotational magnetic field to happen.

Dave do you have any thoughts on the wiring of all these coils?

What do you think of mine?

Dave, resonance might be part of the kicks, anyway wont know until we try.

I'm trying to keep this simple for starters, If what i say don't work, go back and make slight changes and record, as you mentioned.

I think Steven would have done the same, looking for that holy grail.....lol

Sincerely,   

Dom
