To be sure, these electromagnetic time dilations are miniscule for everyday electromagnetic interactions, as are special relativistic time dilations for everyday motion. So testing of dt/dτ changes for electrodynamics may perhaps be best pursued with experimental approaches similar to those used to test relativistic time dilations.

We have I believe discussed this before:

Let me make this plain: Brillouin and others since have raked over the notion of whether electric charges interact classically other than via standard EM theory. The experimental evidence is clear - charged particle inertia thus any possible time dilation/contraction is completely unaffected of the EM potentials.
Example: dipole oscillator as clock, housed within a Faraday cage. Charge up the cage to any desired positive or negative potential, and oscillator frequency will not alter.

If you produce such a number, then we may be able check relatively easily whether such a difference has been ruled out experimentally, or not.

OK, let put out a simple benchmark example. Say we have two charges Q=q=1 Coulomb separated by 1 meter. The Coulomb interaction energyJ.
Yet, if the test particle has a mass m=1 kg, then the EM time dilation is:(1)
This is a very tiny time dilation for a tremendously energetic interaction. The release of this much energy per second would yield a power of approximately 8.99 GW, which roughly approximates seven or eight nuclear power plants, or roughly four times the power of the Hoover Dam, or the power output of a single space shuttle launch, or the power of about seventy five jet engines, or that of a single lightning bolt.
For a special relativistic comparison, consider an airplane which flies one mile in five seconds, versus light which travels about one million miles in five seconds. Here,and the time dilation is only:
(2)
So the EM time dilation (1) is actually less minuscule than the SR number 2. But you need a whole space shuttle to get you near those energies. A Van de Graaff generator at the front of an auditorium in a physics lecture that makes a student's hair stand on end won't even come close to getting you an observable time dilation.

These calculations look pretty impressive.
However, there exist some very stringent bounds on Lorentz violations from recent cosmological observations. You may want to check out those as well:

If one wanted to include those effects, they would go intoin my equation (10), their their impact on the numbers would be far smaller than the numbers I posted this morning, because the Newton constant G is in there. Once G shows up anywhere in a calculation like this, the energies needed for detection grow astronomically huge.Jay
Yablon wrote:Kevin,
As regards empirical data, the most compelling equation in my paper at http://vixra.org/pdf/1605.0259v2.pdf is equation (10). Everything in the bottom line of (10) is physically observed. Had someone just written (10) out of the blue without getting there from the Lorentz force (10) would still be a correct descriptor of the observed energies. So much the better that this is tied to Lorentz force and geodesic motion.
Isn't the third term on the bottom line of (10) for the Coulomb interaction energy of the mass truly observed, and thus a contributor to charged particle inertia just like all the other energies in (10)? However, equation (10) makes clear how minute the EM electromagnetic time dilation actually is. because in
we see that the deviation from 1 is based on the ratio of the EM energy to the entire rest energy which is an atomic-to-nuclear ratio.
I perused the mathematical physics paper you linked, and while it appeared to argue against time dilation, it did so without an understanding of the actual magnitude of the time dilation predicted by (10). If somebody has actually done a time dilation test to the level of precision needed and rule this out, then I guess I'd have to live with that and as Einstein would have said, God missed a terrific opportunity to use a third form of time dilation alongside of time dilation from motion and time dilation from gravitation.
Can you, or anybody, point to specific experiments conducted at the level of precision required by (10), to rule in or out the EM time dilation shown in (10)? Unless the precision of any supposedly contradictory indications was sufficient, I'd have to stand by equation (10).

Q-reeus wrote:Jay, referring to your 2nd last para p6, which presents the kernel issue, no need to electrically charge clocks. My last example of dipole oscillator was a bad one since any inertial mass coupling to an external scalar potential phi will be of equal and opposite sign for the two dipole charges. A linear quadrupole oscillator overcomes that issue, but is inconvenient. All that's needed is an oscillator with large contrasts in charge-to-mass ratios. Atoms fulfill that nicely - heavy positive nucleus, light shell electrons.
We are therefore talking about measuring conceivable spectral line shifts of say a sodium lamp placed in a Faraday cage then subject to varying potential. The cage would want to be well removed from 'ground' for a clean analysis. Given the extreme sharpness of Mossbauer effect, I suppose nuclear transitions might also be viable as check.
An appeal to old Bohr atom will do for this - orbital frequency will go as √(1/m), where m is the net inertial mass of shell electron. We expect emission spectra owing to transitions between orbitals to scale accordingly. This has an important implication apart from observed spectra - but more on that later.
Your 'extreme' example in viewtopic.php?f=6&p=6444&sid=2fc4f4140427851d2b2448bd4a45a710#p6441
seems impressive but as per that last part of 2nd last para p6 in your v2 article, the sole determinant of interest here is ratio (q/m)(φ/c²), and for an electron, q/m = −1.759×10^11 C/kg. In SI units 1/c² = 1.113×10^-17s²/m², so the fractional contribution to electron inertial mass reduces to just δm/m = φ(-1.96×10^-6), with φ in volts.
Not at all difficult to charge up a Faraday cage to several million volts using e.g. a Van de Graaff generator. Are we expecting a dramatic shift in spectral emissions?
Which leads to one more thing, hinted at earlier. As always you are careful to make sure in the derivations everything conforms to conservation of energy. YET - if m can vary by simply immersing in an exterior equipotential (charged Faraday cage), atomic orbitals will expand or shrink accordingly. Not strictly according to √(1/m) for arbitrarily large applied φ, since as m -> 0, SR comes into play, operating on the 'normal' mass component such that things never go 'tachyonic'. In accordance with your eqn (10) in fact. Phew! But even a slight alteration in orbital size implies alteration of the net electrostatic + KE energy. Given the Faraday cage external charge is oblivious to goings on of neutral atoms within, implication is energy can be created and destroyed rather conveniently. Heat up a body external to cage, quickly transport it inside, and capture the shifted spectral emissions as it cools down. Get the idea here?
Anyway, a heap of possible other schemes could be invoked, but - as a patent guy - I'm sure you'll know what to do!

Experimental observation of a change in the rate at which time flows for charged bodies in electromagnetic fields an accordance with (7.1) would therefore confirm this geometrodynamic foundation for classical electrodynamics in four spacetime dimensions.
Q-reeus wrote:Sorry Jay but in all likelihood there will be a rejection from any mainstream journal referee or editor. At least for the main reason given in my earlier posts - the proposed coupling to the scalar potential in particular should have long been observed as dramatic shifts in atomic emission (and absorption) spectra. As mentioned, searches for such or similar effects have long ago been done and came out negative. And as also raised before, any such coupling implies failure of energy-momentum conservation. Owing to e.g. implied changes in atomic dimensions thus net energy - 'virtual muonic atom' orbital contraction if φ +ve, or inverse if φ -ve (made a sign error in my last post). Yet with zero back-reaction (neglecting utterly infinitesimal gravitational coupling) on the causative agent. That is, an electrostatically charged Faraday cage or some such arrangement.
Still, I might be wrong so will be interesting to find out how you do fare.
