So if the wire is held dead-stationary then we get bias.this static voltage should register on the oscilloscopes.basically like shoving a field near an electron-gas in a container.going to cause a constant pressure differential

Look at the sine wave pix. Imagine the left zero (0) on the graph as the beginning and representing 'now' in time.
Follow the amplitude gradually to max (north) then gradually down, past zero (null zone) then on to max south
and back up  to zero. The right side of the graph is 'now', too.
The graph is just showing the potential from pole to pole, thru zero. It isn't really 'waving' (repeating). It's just sitting there. Unless you disturb it.

You can affect a change to the conductor and see on a scope or even in a plasma only if you move the magnet.

Quote frm pinestone'you can affect a change to the conductor and see on a scope or even in a plasma only if you move the magnet'

Or the current.won't the random movements of electrons in the conductor bias toward one direction? Perhaps a massive impendance voltmeter or pico-ampmeter is better to check for this than oscilloscope? It was loschmidt who caused a scene a hundred years ago with his column of air in a pipe affected by gravity.gas molecules accelerate downward and deccelerate upwards giving detectable temperature,pressure(barometer) gradient

It is obvious that there  are trolls who do  any thing to throw off the insightful thinking about magnetvortex and spinwaves by spinning half truths to their own agenda what that may be .. Pun intended...

These trolls are not your friends but are disinformation agents who get money to post per programmed  agendas of some dogmatic science belief, "religion of  science "..

Here is the real truth MAGNETVORTEX SPIN WAVES EXIST AND ARE REAL !! 

Now watch as the trolls will spin this again.. I just makes me sick !!!

Harnessing Magnetic Vortices for Making Nanoscale Antennas 

April 30, 2014

The secret to harnessing spin is to control its evolution and spin configuration.


"If you grab a circular refrigerator magnet and place it under a microscope that could image electron spins, you would see the magnet has several regions called domains,

where within each domain all the spins point in the same direction," explained group leader Yimei Zhu.

"If you were to shrink that magnet down to a size smaller than a red blood cell, the spins inside the magnet will begin to align

themselves into unique spin textures."[/font]

For example, in a magnetic disc with a radius of just 500 nanometers (billionths of a meter) and a thickness of just 25 nanometers,

the disc can no longer support multiple domains and the spins align in a hurricane-like rotational pattern to reduce the overall magnetic energy.



The spins parallel to the disc's surface rotate around a core, much like the eye of the hurricane,
either clockwise or anticlockwise.

And at the core, the magnetic spins point out of the disc's surface, either up or down.

So this structure, a magnetic vortex, has four possible states—up or down paired with clockwise or anticlockwise.

Understanding the interactions between confined, interacting magnetic quasiparticles, such as magnetic vortices,

is essential towards developing both an understanding of their mutual coupling, as well as limitations for a variety of spintronic devices.

However, due to a lack of spatial resolution afforded by traditional techniques, direct observation of the changes of vortex orbits in real space has been lacking.

Utilizing high resolution Lorentz TEM, we image the time averaged vortex trajectories in multi-vortex permalloy rectangles and ellipses while applying an oscillating in-plane field tuned to the vortex gyrotropic mode.

Using an additional in-plane DC field, we observe a transition of the vortex orbits from circular to heavily distorted as the vortices are driven together, a result of increased interaction strength in laterally coupled vortex pairs.

Furthermore, in closely spaced vortex pairs, the strong coupling results in a single resonance frequency.

As the vortices are moved apart, pinning effects begin to dominate, and the peak frequency is no longer singular. Micromagnetic simulations are utilized to further elucidate the coupled behavior and obtain time-resolved information of the dynamic process.
