fun observations about the magnetic field

[barbosi]

C'mon tk, why did you have to bite?

This is fundamental, it is entirely calculatable, it is contained in Maxwell's equations

Maxwell equations are great but do not reflect conservation of energy. Look at the graph http://en.wikipedia.org/wiki/Maxwell%27s_equations#/media/File:Electromagneticwave3D.gif and tell me why B and E fields are max or zero at the same time and how that applies to (or respect) the conservation of energy. At ZERO there is no energy AT ALL. How both fields reborn? Phoenix (the mythical bird) effect LOL?

..., and it is how the CRT designers make the electron beams hit the right places in the face of the CRT when it is displaying an image. Have you ever taken apart a CRT monitor/TV set?

I'll save this for later to give you time to study the "S curve" of electrons' beam and we can debate it when you truly understand it.

An additional question is about the water in the video i suggested. Any idea why vapors have the swirling shape?

You sound and your confidence surely look like a well grounded into proven facts type of professor, but I'm willing to challenge you only after you answer my two questions: Maxwell and my proposed video.

Or just accept your boss' slap and fade away (it's just a pay check and your value can draw income from somewhere else).


Toodly-oo....

Your "Conservation of Energy" strawman about propagation of EM waves in space has very little to do with your original bogus misrepresentation of what goes on when a magnet is placed near a CRT, since electrons are not photons and photons are not charged particles. Have you ever heard of the quantities μ₀ and ε₀ ?

I doubt if you have the necessary  math to understand it, but here is just one of many references you can try to absorb, concerning Maxwell's Equations, propagation of EM waves, and conservation of energy:

Yes, I certainly do know why the circulation occurs in the magnet-demonstration. But you evidently do not.

The people who design CRTs and electron microscopes and many other devices certainly do understand the "S-curve"  of electrons in magnetic fields as you put it, since they make them reach their desired targets very accurately and so consistently that the devices that perform this magic can be mass-produced by the millions... and these engineers would be laughing in their beers at reading your comments. The very chips that make your computer work are manufactured by producing, carefully manipulating and accurately directing beams of charged particles using time-varying magnetic fields according to the relationships condensed into Maxwell's Equations and the Lorentz Force Law. So if you want to "debate" these facts I suggest you do it with a chip fabrication engineer. Why don't you stake your next paycheck on the outcome of your "debate"? It's just a paycheck...

tk,
I thought you brought Maxwell into discussion. now I have to go back and check.

However the law about conservation of energy still applies and your share with the pdf document is much appreciated.
I particularly enjoyed the conclusions on "Liénard­Wiechert potentials" which lead to Conservation of Energy and Momentum        (Jackson sec 6.7)

In essence it means that having parkinson disease can have some advantages, namely one can scrub easier the ceramic tiles, especially when is p!ss all over the floor.

your truly,
max well

Magnetic strength is only as good as gravity will let it travel.
The balance between the two , is very hard to find.
If you could loop a mag track is , that perpetual motion?
