@Jeg

Have to say thanks for the pdf.

Attached it here.

Yes, thanks for the pdf  Jeg.    When I was about 10 or 11, there was a book at the library that had shown the same as the pdf, but not as extensive of complete understanding as the pdf. It was an old book then and Im 48.  It was a book that had all sorts of electrical and electronic projects.  Never built it.  Didnt need one at the time.

When I was in electronics school after 3 years at VoTech, the theory teacher exclaimed that there were no magnets or electromagnets that were able to attract copper, aluminum and such, as we were on the subject at the time.  I put my hand up and told him it wasnt true.  And he argued strongly against my assertion.       The next day in class, I had that book with me, as I commuted to Pittsburgh at the time and the library in my town was blocks away.

Once he had looked at it, he conceded that he had never heard of such a thing. But didnt deny an anyway that it could work, and thanked me for bringing the book that day.

So it is not common knowledge really that it exists.  Can anyone show a device or machine that uses such a coil? Its possible that it is used out there by big companies, but still, not in any Educational books that I have ever encountered. There may be some, But I can say that in my 5 years of electronics back then, I never met anyone that knew about it either till I had shown it to them.

My Mom used to like to play Bingo at the fire dept, and she brought me and my brothers along sometimes. There were lots of other kids there also so it was a fun time for us. This was before I had seen the library book. Just a kid.  There was a lady across the table that used dimes as chips on her bingo cards.  And when someone yelled BINGO!  she would swipe a plastic box about the size of a deck of cards over her cards and it would pick up all the dimes.  <--- Me  And later when I had read the old book, I was reminded of that Bingo dime box immediately.

I was about 8 at the time. My dad had got me 2 electronics kits around then, a 150 in 1 from Radio Shack, and the other was less listed projects, like 35 or so, but had components on plastic squares and a peg board to mount them. Each had 4 pegs that the wires clipped onto for connections.  So I had some knowledge of electricity, electronics and lots of play with magnets.  So the plastic box that picked up the dimes was a big surprise for me. I never asked her about it, I was shy. But I watched and imagined.

So this thing is old. And the only device I know of that could possibly have used this electromagnet config would be that dime Bingo box. Anybody ever see one?   There were also bingo chips that were translucent, mostly red, with metal rings around the edge that a similar looking box with a magnet would be used to pick up the chips.  I could not tell if the dime box had a switch/button, as I wasnt really looking for one as I thought it may have been a special magnet. But now, it probably had a side button, which could be used to drop the dimes easily in the container they were brought in, where the regular magnet box and translucent chips would have to be slide of the bottom of the pickup box with the standard magnet using their other hand.

I suppose playing bingo is a bit of work, considering people invent ways of playing it more easily to avoid picking up all the chips, pennys, dimes, by hand, off of all the cards they are playing once the individual game was over to prep for a new round.  So if there was a company that made the Dime box, it was probably a good selling point as to it was one handed pickup of all the coins, and a release button.  Now thinking about it, its possible there were 'electromagnet' translucent chips with metal rings pickeruppers so they could be easily dropped also. But the ones I had seen were manual peal off, 2 hands needed. 

Anyway, Just wanted to share that.

[/font]Even though no one has posted here for a while, I was led here from another post and felt I just had to comment because there seems to ALWAYS be a LOT of confusion about Tesla's comments about BiFi coils.

First, Tesla is referring to Flat coils for the most part.  A standard coil wound BiFi has the almost the same type of effect, but would be a lot more complex to understand.  The stray cap values introduced in a standard wind will be hard to determine, but the crossing of the cap values does destroy part of the effect.  I won't get into those details for this, but be assured I have done my research here.

So, using a flat coil, wound normally, the internal cap value is from 1 turn to the next, as stated by Tesla in his patents.  (100 turns, 100V, 1 Volt per turn!) Simple to see, right?  Now wind BiFi, and connect in series and the picture is that the cap value has 1/2 the entire voltage across the coil ON EVERY TURN.  (100 turns, 100V, 50V per turn!)  This is on both sides of every turn, as well.  I forget the number, but Tesla stated that it was somewhere in the order of 200000 times the energy storage.

If this doesn't explain the reasons for the increased power, then there is nothing I can do.  It should also explain why a standard coil (solenoid type) has a different effect, as the windings on top of the layer below DO NOT have the entire 1/2 the cap value, so the internal interactions drastically decrease the external effects.  (Try to imagine the larger cap values forcing small areas to reverse the flow and this should be obvious...)  That little bit of info is from testing, not reading.  I guess This will be ignored anyway, so I hope this info helps someone...   Also please remember that open-ended coils are not linear with respect to current.  (I.E.  Different currents will flow at different points in the coil, contrary to what is taught in basic electronics.  More advanced learning describes this, but not in such a simplified form.)

Since we got to talking about pancake coils
I was playing with a large speaker magnet and a magnet sphere,  if the sphere is in the center of the ring magnet it seeks the inner edge, the magnetic field tends to push the sphere out of the magnetic field.

I was wondering how a pancake coil would react in the center of the ring magnet would the magnetic field do the same with the electron, push it to the outside,

Isnt this how an electric motor works the magnetic field tends to expel a current carrying wire.
Would the magnetic field accelerate the electron, trying to expel it.
There should be no bemf, just forward acceleration.

 Again let me show some light on the problem. One thing about nature is it doesn't need cables or wires to work. Why is that? Here is my approach and the approach of the new scientists we see today:

 Please watch this and really open yourself to the facts of what we see and the innovative explanations of the natural process from the newest breed of scientists.

Hello Tito


Goodbye Lenz.


How is the class doing??

There is actually a very thin line between facts/reality and pseudo-science/snakeoil.,

http://www.purative.com/2012/01/scientists-say-dont-be-duped-by-alkaline-water/

Decide yourself, Aviso dealing in alkaline water is a non scientific man and so is his motor and inverter. Thats why still not approached by Nissan and Tesla Motors.

I will again be shunned by his fans who blindly believe that he is right. Right ?

Right !

Google:- I think it's about time that the human rights of snake oil salesmen was protected.
Snake oil selling  is a reputable business as is the business of those who don't know the
difference between their asses and a hole in the ground. lol


Seriously though it's nice to hear from you again.


I always had my suspicions about Aviso which is why I asked the million dollar
question.

Thx king, You know I am a bad guy coz am too blunt and cold blooded. I do a lot of pooh poohing.
