Is Tesla longitudinal or transverse

[teslatek]

I read many articles saying that Nikola Tesla's wireless energy and wireless communications were transverse and not longitudinal. They state he was using the near field and far field. Articles such as this: Tesla's Big Mistake? . Do you have any counter arguments to refute the near field arguments? Insight and thoughts will be appreciated. Thank you.

Tesla is very clear that his wireless is longitudinal.

Tesla has become almost godlike in our minds. We all need heroes. Tesla is one of mine. Obviously he knew more about electromagnetic waves than anyone else around. But consider this: think of the power it takes to generate a tsunami compared to the power it takes to generate a typical ocean wave.
There is a huge difference. He went to Colorado Springs to find out if lightning bolts generated longitudinal waves. Apparently they did or he would have given the idea up and gone on to develop other brilliant ideas.

This is why florescent bulbs light on the sides of a Tesla coil if the Tesla coil had a ferrous core the waves would be all longitudinal.

An air cored coil puts out transverse waves.

A ferrous core puts out longitudinal waves.

A toroid core puts out a transverse wave but it does not propagate away from the core at least not far, only as high as the field strength

[Dave45]

A toroid produces a transverse wave but because of the ferrous core the propagation is not away from the core but circles the core

In a typical solenoid we see a longitudinal force and a huge current draw to
go along with it. But a longitudinal wave in the ether?

Conventional physics would simply laugh at even the notion of ether.
The only way to know for sure is to measure longitudinal waves.
Anyone besides Tesla done this in a clear easy to replicate way?

The electric field circles the toroid unless there is a conductive path through the toroid.

Think smoke ring

[wyndbag]

smoke rings.... solitons..... energetic waves without real mass.... I will keep thinking that..... must have been having a senior moment. Thanks Dave M

[teslatek]

Need the math.

Sorry everyone. I should have been more explicit. We need math to prove this. Eric Dollard did and article with the proper formula but used sound waves instead of electricity. The two papers that refute Tesla must be defeated by math.

"Think smoke ring"
That is a neat visualisation Dave - for a circularly generated field, or even EM radiation.

However EM radiation is NOT waves, whether imagined as being longitudinal or transverse.
Thinking of EM as a 'wave' is a concept which closes your mind to further possible developments !

There is no wave prior to the EM radiation being transduced.

It is the reception/transduction which develops potential differences capable of being described as if having been induced by either longitudinal or transverse excitation.

So what is it that your 'smoke' is mirroring ?

Plasma ejection, but the smoke ring is actually not a good representation a spring would be more relevant if you had a resonate lock with another coil, if no resonant lock then smoke ring is more appropriate.

A ferrous core puts out longitudinal waves.

Could you provide more information as to why this occurs? Have you discovered this in your own research?

[Dave45]

Here's the reasoning behind my statement, a tesla coil puts out a transverse wave along its axis

because it is air cored
but with an iron core the field follows the core like in this vid

[Dave45]

notice in the vid the aluminum ring is tilted, this would be how we would expect it to act with a field that had a spiral configuration.
