Joseph Henry (1797-1878)

There is some good reading that can be found on Google books regarding one of the pioneers of electrical induction. One book in particular is called "The Scientific Writings of Joseph Henry"

This isn't really a discussion thread (at least for me) but used more to provide an avenue of undiluted information from the dawn of induction. Some may find his writings useful and perhaps his work leads to new discovery for you. For others........ well....

Here is a small section taken from the book. Enjoy the writings of this very important pioneer.

Ok, let discuss it please. What is the cause of "giving shocks" ? It may answer and describe the difference between those two "kinds" of induction.

It sounds like a capacitive effect but it would be hard to tell without seeing some type of detail of the set up.Rapid make and break would simulate an uneven alternating current accounting for the back emf on the break being a higher voltage as the stored field collapses quicker then it was created due to the difference in resistance for the separate conditions.

to my simple mind it goes like this : I can get shocked by a current flowing through my body, and current can only flow when there is EMF force or potential difference (voltage)....
current which can deflect voltmeter needle but not produce shocks, is either:
1. a too high frequency current (I doubt it was such in case of Joseph Henry experiments)
2. has non-electric nature (yet still has magnetic component, because it deflects voltmeter needle)
3. has no potential difference (voltage generating current) between source (apparatus part) and my body , yet why it does still affect voltmeter ???

The difference between these two types of 'induction' is explained in a lot more detail in
this 'Transactions of the American Philosophical Society' document:
"Contributions to Electricity and Magnetism. By Joseph Henry, LL. D. Professor of Natural Philosophy in the College of New Jersey, Princeton. No. IV. On Electro-Dynamic Induction."
(Source: Transactions of the American Philosophical Society, New Series, Vol. 8 (1843), pp. 1-35)
http://www.jstor.org/stable/1005226
PDF download from here:
http://www.jstor.org/stable/pdfplus/1005226.pdf

It looks like what Henry did was have a flat coil made of a coil of copper ribbon as his main (primary) winding,
which he was connecting to a battery, and a separate helical (secondary) coil winding sitting on top of the
flat coil. He was using the helical (secondary) coil terminal wires to feel for shocks made when he pulsed the battery
connection on the flat coil. Depending on the exact coil arrangements and battery voltage, he was getting strong shocks
in varying degrees when he first connected the battery, and when he released the battery connection.
What he did was place a zinc or copper plate between the flat (primary) coil and the helical (secondary) coil
and found that if the plate extended far enough outside the edges of the two coils that it would stop
the shocking when connecting and disconnecting the battery while someone was holding on to the helical coil wires.

In contrast to this, if he used a magnet or an electromagnet coil as the primary (he didn't use the terms primary and secondary coils
as that terminology was probably not yet in use at that time), and moved the secondary coil in and out towards the magnet/electromagnet,
it would also induce a current in the secondary, but putting a zinc or copper plate between the magnet/electromagnet
and the moving secondary coil would not block this type of (magnetic) induction. Henry surmised that these were two
different types of 'induction' then.

Knowing what we know today, it seems possible that in the case of the 'first type of induction' with impulses from the battery
being suddenly connected and disconnected, that he was actually seeing a capacitive effect between the two coils, as Doug1 suggested,
which transferred the pulse except when a large zinc or copper plate was between the two coils. Not sure that is the correct explanation
however. It is quite interesting to see how they approached their experiments way back then.  :)
All the best...

forest,you have not ever to be skocked about electricity but sometimes also about the kind of use:
Joseph Henry invented one of the first electric news teleporting apparature,
the"Morse Alphabet" short-short-.. telegraph.


Mr.Morse "only" invented the alpha-beta,"the transmission language".


How worked the first "Henry telegraph transmissor" prototypes ? Probably the real physical construction shows his ,above  offered ,meanings ! Shielding/Isolation.

 Also William J. Hooper found a different field which could not be shielded. Perhaps you may find some interesting details into this link:

Hello,

this is a link to a german website http://www.pro-physik.de/details/news/prophy10910news/news.html. Some french researchers have proven that the A-Vectro-Potential is the cause foe induction in certain cases:

This same proposal is stated in the paper "Electromagnetic Induction without a field" by Monstein. He states that the real cause of induction is the A vector, which is real, and the B field is just a non-existent convention used to visualize the magnetic field.

A link to the PDF of the refered paper:
http://www.overunity.com/14711/is-faradays-induction-law-correct/dlattach/attach/139244/

Monstein´s work, as far as I know, has relation with the work of William J. Hopper:  http://jnaudin.free.fr/html/hoopmnst.htm

Also an interesting compilation of info about the A-vector. In the bottom of this page there is a very enlighting video:  http://www.hyiq.org/Research/Details?Name=A%20Vector%20Potential

This area [thread topic] shared by Fernandez is being looked at
as well as his most recent contribution below .[IMO all his contributions should be looked at]

I would rather suggest, the Kapanadze, Stepanov and Barbosa-Leal devices are just open electric systems. Such a system simply defeats Lenz's law and Ohm's law by connecting to the ambient medium as a source of energy.


response from Fernandez

User Zeitmaschine, I am going to give you credit, you put a lot of effort into your posts (even though you are wrong) BUT I want to put you and some others in this world on the right track and moving in the right direction.


Fernandez Quote

Here is the truth, take it or bury it
I will keep this short and drama free, the words Free Energy, Overunity, and Zero Point Energy has corrupted your thoughts because the device is............ so easy you will laugh

For starters your statement is incorrect Lenz's Law is actually a blessing, you need to wrap your head around that first. Let's review Lenz quickly



Quote

An induced electromotive force always gives rise to a current whose magnetic field opposes the change in original magnetic flux.




All of you globally have missed the key word in that statement, you are too quick to denounce Lenz's Law as the culprit, the destroyer of energy. However, if I highlight just one word in that statement we open up a new method of utilizing Lenz's Law.



Quote

An induced electromotive force always gives rise to a current whose magnetic field opposes the change in original magnetic flux.




So the beauty is, if I create a magnetic field in a coil with some current NATURE rewards me with a duplicate magnetic field that opposes mine. Already I got something for almost nothing. (BTW... that's my first Primary coil usage, to create a Lenz induced field)

So I now have a Primary magnetic field that gave rise to an induced magnetic field as stated by Lenz. Pay close attention here, this is important! Now take another coil (call it Primary 2) and feed your Lenz induced magnetic field so you complement its growth. So in other words your North pole of Primary 2 faces the South pole of Lenz field (or Vice Versa). Because Lenz is only present in change of original magnetic flux. Are you starting to see? Lenz has no interest in my second Primary because Primary 1 is the parent of Lenz induced field. You really need to appreciate how powerful that statement is. Ignore what has been written in any other thread that talks about these devices, lots of people using big words and way to complex algorithms to build something a child can assemble. 

So do you now understand why Barbosa and Leal explain in their patent the pole of the induced complements the primary pole? Do you now understand why that guy Tariel says........ it's so easy you will laugh, see why Clemente Figuera said "this is like the egg of Columbus". Because it really is that silly and simple, you simply feed the induced magnetic field with another magnetic field. There is no Lenz that opposes Primary 2, Primary 2 doesn't create an induced field (if you time it right) it ADDS to what has already been induced from P1. The result is a strong Rectified Magnetic field. That is your resonator, not so glamorous now that you know how everyone including Steve Mark pull this off. I apologies if you where looking for something more complex or other worldly. Unfortunately many of you will still be looking for a more complex solution because your mind will never accept such a simple solution to a problem that had you perplexed for years.

That is the theory behind the how it works some of you are smart enough to figure out the build details, but I will get you started. You are going to wind you primary's like a Poly-Phase motor (Yep a Tesla invention) take special note that a capacitor is used to delay a phase (this is super cheap and EZ). These devices use impulses and you need to split the wave in half so diodes are used. So one coil is at its magnetic max while the other is not, also you need to split the wave between coils, so half wave per primary but that is why you are using diodes (or tubes if your that type of guy Steve). Timing is very critical between the coils, remember you are building a resonator and nothing more.

Like I said before, take some iron from a tire jack and cut the ends off. Get a C-clamp to close the ends and you have a simple core that allows for different coils. To extract you need a secondary but that is simple, wrap it around your low budget iron core, use a thick or thin secondary.

So its up to you and figure out if the primary's should be CW or CCW, shouldn't take that long. BTW... bifiler coil doesn't mean crap.  The beauty of this device is different inputs (voltage/frequency) changes the output and output varies based on type of coil. Start simple, low voltage and don't kill yourself. You have more in this post then you ever wanted.

One more thing, Tesla patent, 413,353 not glamorous and not your FE but excellent facts and my personal opinion is as close as it gets for Tesla. 

haven't taken the hacksaw to the tire iron yet

some fellows/members here are  getting ready
and it will happen in a dedicated thread when it does

Long ago, a decision was made, to separate the two electricities.
Prior to then, electrical machines contained both types.


Today, the remnants of this are only seen in static electric machines.


You can look at machines of the past, and there you find two storage components.
One positive, one negative.


The machines of today only contain the negative (we label this + volts)


They are distinctly different in appearance, form, and properties.
