Hey, guys.  I'm on a long family trip, by car, visiting relatives in Michigan, Maryland, Penna, etc. and away from the lab TOO long.  But I've been thinking more about the Faraday paradox and the following -- which also appears to be paradoxical.  I posted this question on a physics forum, no response yet. 

Can anyone provide an answer?
I'm a retired Physics Professor, and this is an important question to me... but I admit I'm stumped....  unless I give up the idea that momentum is always conserved in electromagnet devices....  ;)

Thought experiment I.

Consider two loops of wire, 2 small dipoles B and C , with a common axis z (facing each other) and (say) 30 cm apart B to C. At the speed of light, information (including a change in magnetic field) will require 1 nanosecond to travel from C to B.

1. Have the current on in coil B for some period of time at the start, so the B-fields at C is established in the +z-direction.
2. Turn loop B off rapidly (fall time < 0.3 ns, say) at the same time that a current in loop C is turned ON (rapidly, rise time <0.3ns, and opposite sense with respect to the previous current in loop B ).

3. In this way, as the current is turned on in loop C, it is immersed in the field from loop B and therefore both receives an impulse to the right, in the +z-direction.

However, loop B will be "off" (and open so no effective eddy currents) when the "return" field from loop C arrives.

Thus, loop C (which is free to move) will experience an impulse giving it momentum in the +z direction (to the right), whereas loop B will not experience an impulse to the left.


I think this argument is sufficiently simple to sketch and to ponder.

Thought Experiment II.
However,
If you argue that there is momentum to the left "in the magnetic field" from loop B, I will add a third loop to the left (call it A), and again, as B is opened rapidly (short fall time) -- at the same time that a current in A is turned ON (rapidly, and SAME sense with respect to the previous current in loop B ).

In this way, loops A and C (both free to move) as they turn on are immersed in the field from B while having currents in the opposite sense -- therefore BOTH loops receive an impulse to the right, in the +z-direction.

Oh, and I will need to turn off the currents in loops B and C rather quickly, so that they both receive impulses in the +z direction without "feeling" the B fields from each other, for they will be "off" when those fields arrive.

If you're concerned about fringe fields, I can add a rod of very high magnetic permeability down the z-axis, extending from A to C, so that essentially all the magnetic field is contained on the z-axis.

Whew -- simple thought experiment, but one that could actually be done IMO.

What will happen? Will there be momentum imparted to the right, but not to the left?

Hey, thanks for thinking about this with me.

SM never used the word antenna.

Two large loops one facing the ionosphere and the other the planet. Static or white noise from ambient environment amplified and fedback into the magnetic bias of the large loops. Effective aperture.

Only 100 times?   oh how sad!   :(

I can amplify noise 1000+ times with a good high Q resonator!


Professor is talking about electromagnetic field propulsion, my favorite topic!  Yes fields carry momentum.

EM,

I would like to see the amplifier you would use to amplify a signal below 100 K (That's 'Kelvin')  :)

And the good Prof's idea has a good deal of merit, in my book. However, I think we would find that magnetic and electric fields not only carry momentum but 'ARE' momentum  ;)

Each being momentum of the other ( OK I will shut up now  C.C )

WW,  I have seen resonant tank circuits with Q values on the order of 100 000    :o

And why operate at 100K ?   We could, but hey there's more noise energy at 300 K   ;)  

   
Group: Guest
I suppose they were shooting for under 100K because that is about as close as many could go on the way to ZPE.

If so, any amplifier used would need to operate below that temperature or the target energy would be lost in the amplifier noise.

As far as Q goes... the more the better - sometimes. If we were trying to collect such low level energy I think we would need a very wide-band system. Since higher Q normally means more narrow bandwidth I think high Q wasn't in their plans for collecting ZPE.

300 K? Yes, more signals but less energy  ;)

High Q gives a very nontenuous field that will receive the excitation of the charge that envelopes all...

A1 pumping standing electromagnetic wave with a high magnetic field strength at the positive polarization of L1 to break in time for the "pull" of the positive charges in the mode of resonance, and creating conditions in A2 by the compensation inductance L2 of the upper half for the induction of an electromagnetic wave in it with minimal loss of power Don has achieved the required strength of the magnetic field induced by the current wave of nodes in A2 to capture the positive charges. In a standing wave as we all know the form of voltage and current nodes, where the current and voltage almost pass by value in each other. Therefore, the current node at resonance is quite a powerful magnetic field. In essence, this powerful magnetic trap in a mode of resonance has a lot of "space" to capture particles. Connecting a bank of capacitors, designed by Don Charging a cold shock to the traveling wave regime to A2 (traveling wave is formed in agreement with the output impedance of the source-impedance load) Don received a transporter for a cold current in the form of a traveling wave in the A2 and the capacity for accumulation of power in the form of battery bank of capacitors C3, a traveling wave.
