Muller Dynamo

[xenomorphlabs]

Plengo that's a rather interesting video on standing waves bud first time I've ever seen that one do you know what type of devices they are using to create the waves? To me a standing wave would only be good for short distance by looking at this because it would take lots of energy to slosh the ocean back and forth like that a small tank or cup of water sure there are also rouge waves in the ocean that people have be studying recently I wonder if there is any relation. I see where you might be going with the standing waves for the muller device but it is tough to say for sure you would think somehow we could find a way to see them.

Thanks for the video...

The nodes in a high voltage coil can be "seen" with a neon bulb placed at the nodal points along the coil.
The voltage in the Muller coil is too low for the neon, but if you see a frequency-selective voltage maximum on your oscilloscope, you can be sure you have resonance (which is basically the condition that forms standing waves).
Like Itsu said, there might be a lumped element too much in the circuit (rectifier)
for this to work.
Gotoluc has shown generator coil resonance with just a cap added though.
The question is, if standing waves across the coil only happen when the wavelength of the generator frequency corresponds with the coil length (e.g. 1/4 lambda etc.) or if with an added capacitance in series LC resonance the coil/circuit also exhibits standing waves somehow.

standard magnets don't exhibit a Bloch wall in their interior.

LOL ... define a "standard magnet"

A standard magnet is any magnet that is magnetized to exhibit a single magnetic moment (a macro-domain if you like). That covers 99.99% of the magnets used by "consumers" and FE researchers.

A "Bloch wall" is a transition region which exists between any two magnetic domains which are not oriented in the same direction. The most common type of Bloch wall is the 180º wall separating regions of opposite magnetization and found in many ferromagnetic materials (eg. thin films).

Attached is an example of a block of ferromagnetic material magnetized with two opposing magnetic domains. The "Bloch Wall Region" is clearly evident.

LOL, I knew you'd respond post haste, being the stickler for technicalities that you are. Good on you by the way. And yes technically you are right.

The "bloch wall" is actually a microscopic "entity" with it's description rooted in the world of magnetic domain theory.

In the real macroscopic world, where EE's design and make things, and theorists take a back seat, the term, bloch wall, is readily accepted as referring to the "null magnetic region" in a magnet where N + S vectors are equal, and cancel out. Also often referred to as the magnet's neutral region.

The term bloch wall is not restricted to just magnetic theory, it also appears in optical theory.

It's a bit like the abbreviated term: BEMF, which in conventional electric theory is a term often  used within the same document to describe two different things. That's why some people say Flyback or CEMF (collapsing field events) or Counter EMF (motors) to differentiate the type of BEMF they are referring to.

On my site I describe the bloch wall as the magnet neutral zone to make this distinction.
