No, you misunderstood me. I presented a reasoning. When the cause of vibration comes from internal forces then the system (ring) should be able to move or vibrate due to Newton's 3rd law. It is Newton's 3rd law that does not allow motion by means of internal forces, not me. 

Regarding the net work of internal forces, it is clear the net work of internal forces (since it is zero) cannot trigger system's motion. Everybody knows this. It is derived by Newton's 3rd law: ΣW = WA + WR = 0 (work of action pus the work of reaction equals zero).

 

When you jump in the air, you use your muscles. There are connected only to your bones, i.e. they act purely internally.

How do you account for your ability to jump in the air?

Action and reaction forces act on different bodies, so it’s nonsensical to do this math.

It’s like saying energy is conserved, so nothing can move.

We speak again for an isolated system. An action exerted upon a part will create a reaction upon the rest of the system. Consequently, due to Newton's 3rd law the isolated system cannot acquire a momentum by means of internal forces.

I don't understand what you mean here? I consider the ring as an isolated system being influenced only by the internal magnetostrictive strain that means an isolated system powered by internal forces, according to Newton's 3rd law will never acquire a momentum. It is the same when one tries to lift himself by its hair or pushing a car while being inside (see LEGO car with the ring). 

But it's not an isolated system, that's the point.

So you keep saying, while repeatedly ignoring my request to reveal where you “learned” this (part of the issue: is the ring an isolated system?)

Also ignoring examples you can see, e.g. a person jumping into the air

By contracting and expanding your body that means by redeploying the center of gravity of your body which creates a force that is in essence external to the body.

How can the centre of gravity of your body move, just by the action  of internal forces? Haven't you spent the last fortnight telling us Newton's laws say that can't happen?

In terms of what force is being exerted on the ring, we agree that is internal (magnetostrictive strain). Consequently, the cause of ring's motion is essentially internal that means its motion can be justified as being an isolated system although is found inside a gravitational field and upon a table that both does not make sense of being the cause of system's motion (from the moment the cause is internal), as I described above.

Yes, I did when I was speaking about motion of an isolated system powered by internal forces. The body of a person can never propel itself e.g. if being suspended by a thread or in absence of gravity or by not touching a surface (in order to take advantage the reaction force from the surface).

The system is not isolated. As I wrote earlier you have metal items around and the table may not be perfectly horizontal, so the magnetic and/or gravitational forces may be responsible for the slide/momentum.

Because, unlike you, we like to get one thing at a time straight, instead of continually lobbing in yet more complicating factors in order to obscure the analysis of the problem.

This is out of question because I did the experiment (see first posts). As a direct proof of not being the case you have to watch besides the LEGO car experiment, the rotating ring which its rotation is absolutely controllable (increasing frequency -> clockwise rotation, decreasing frequency -> counterclockwise rotation). Consequently, it has nothing to do with your claims.

OK, so does that mean you recognise your body, when you jump into the air, is not an isolated system? And that, when a system is not isolated, internal forces can cause it to move?

The most complicating factors exist on the ring moving across the table which brings much controversy. This is the reason I suggest to check the other two which are clearer as set up and observed effects.

No dice. I am still trying to get you to be clear about what happens when you jump in the air. So far, you are not managing even that.

I just make a parallelism regarding the cause of motion. According to Newton's laws of motion, a body or a system may move by means of external forces. According to my understanding regarding the experiments and what we have agreed so far my personal conclusion is that the system moves by means of internal forces as being an isolated system. That is all!

This is your point of view and it seems you don't like to confront the issues because you are focused of what I cannot manage, so you think let us take advantage of it and nail him down, right? I don't care. I am not a physicist and I do not claim physics is wrong. On the contrary, I put the material on YouTube and open a thread here in order to discuss it. Each one of us besides knowledge and expertise in our fields, we have some brain and can think in our feet by presenting logical arguments.

In this case the vibration is less important (the car has wheels) and it hints that magnetic forces (from the metal items around) are more probably involved.

The third experiment also suggests that the magnetic forces are responsible for the slide and not (or much less) the gravitational force.

About the LEGO car: If you watch closely, you may identify the ring attempts to rotate and while doing that it is blocked by a LEGO piece in front of it. What happens at that moment, the ring seems to push the LEGO piece (being a part of the entire car) that leads to entire LEGO car motion. How Newton's laws may explain this? I cannot find an explanation according to Newton's laws. The only thing I may confirm is the ring attempts to rotate that means a tangential force is at play originated from inside the ring. This can be proven by the Exp #3 with the controllable rotation of the ring.

In Exp #3 we may clearly identify the tangential force created by the ring, otherwise the ring wouldn't rotate. Again, there is no interaction with nearby metals or table feet. Note: We speak about a 200 grams ring with high a magnetic permeability (almost all magnetic lines are found inside the ring). See datasheet in my initial posts.

Because making the system more complicated will not clear up your misconceptions

Now replace “body” with “ring” and you’re one step closer

No, “we” did not agree. The vibration is caused by an external magnetic force, and the table is exerting a force.

You took it wrong. The simplest system is that with the LEGO car since it does not touch the table and just pushing the car. So, how something may push the car while being inside? What Newton's laws of motion say about it?

A simpler system has fewer components, not more.

Then stop saying Newton’s laws don’t allow the motion you observe. That’s the same as saying the laws of motion are wrong.

I have explained myself how I put it. If I am wrong, tell me how the LEGO car is moving and what Newton's 3rd law says about it? Gravity and table vibrations have nothing to do with the LEGO car therefore, those claims cannot hold as main cause of motion.

No, I will not examine the complicated system when you will not acknowledge the analysis of the simpler system. This is a version of the Gish gallop, and is a bad faith argument, which we won’t tolerate. Deal with the simple system, or we close the thread.

Again it is not a complicated system in terms of demonstrating the effects. You haven't answered my question regarding the force that comes from inside the ring is internal and then I put another argument that the ring shouldn't vibrate according to Newton's 3rd law and nobody said anything about. Something else is happening or something else obscures the effect according to my view. Therefore, I suggest you to watch the example with the LEGO car, it is clearer (no table vibrations, no gravity influence etc).

So, who is in bad faith? In front of experimental evidences that need serious discussion, your only interest is to close the thread because someone presented some logical arguments that do not comply with what you serve (physics). Do whatever you like.

Well, I'm not sure, but it still may be the gravitational force to blame. It seems that when friction tends to zero, due to vibration, the ring is sliding to the right, in all experiments.

The rotation may be caused by the red tape: the friction appears to be greater between the tape and the table than between the metal and the table ... There are also some forces from the cables ...

In order to understand it better, you should: use a bubble level meter (to be sure that the surface is horizontal), reduce the tape/cable rotating effect by "gluing" the ring on a "plate" and minimizing the tension from the cables, and last but not least, remove the metal items around.

I asked “Why do you think a coil of wire exerting a magnetic force on the ferrite ring is an internal force in the ring?”

You have no credibility so “your view” is pretty much impact-free

You have been given serious discussion, which you ignore or reject, and you have not presented logical arguments; your posts are a parade of argument by personal incredulity fallacies.

“comply with what you serve (physics)” is what we mean by “general appeals to science being flawed or dogmatic” in our rule on bad faith arguments.

As I said before, we’re not discussing this. What he should do is learn Newton’s laws of motion by investigating simple systems
