Assume a conductor in a rectangle shape for simplicity.
Now, if I only choose one side of this rectangle, and apply external electrical field ∑ only to it, what EMF would I create on the conductor? I would simply say ∑, however then I had the following idea, and I started to doubt if I create...
Thanks for clearing that up. One last follow up question:
If experiments shown Faraday's induction law to be formulated differently, say some weird physics law like "increase in current has a cubic effect, increasing Area reduces induced EMF etc", we would still do the exact same thing then...
Can you suggest an example for Faradays Induction Law? Are we able to define it with using only common sense starting points such as charge and mass conservation
(but not gauge symmetry nor flux conservation as they are more abstract ones. I mean I cannot ask why flux conservation took place...
I see, then we could not have Maxwell's law without Faraday's Induction Experiment right? It all boils down to this discovery along with discovery of Lorentz force.
I am having trouble with deducing the origin of Maxwell's Laws, especially Faraday's Law. Obviously some of the laws has to be originated by experiments and the rest should be mere deductions.
I would guess that Lorentz force law is the empirical information where we just named some terms as...
I see, so Current*Magnetic Constant is what we can observe, that is the thing fixed.
And we define magnetic constant indirectly choosing an appropriate unit for current. And we especially choose Amperes to make magnetic constant 4*pi*10^-7 but we could have chosen a different current unit and...
I also thought derivation should have something to do with geometry, that indeed makes sense. But still, since we do not get to choose magnetic field arbitrarily, how did it happen to be 4*pi*10^-7?
I am assuming there should be a justification behind. What is the constraining laws for...
But it has experimental results, we cannot define it arbitrarily. For example when there is an infinite line carrying some current, we calculate the magnetic field using this magnetic constant. Then when there is another charge moving around, it experiences a force caused by this constant. So we...
Why magnetic constant is specifically 4*pi*10^-7? I can understand other experimental values, for example it would make sense if it was 3.1415*10^-7. But 4*pi is something we can never confirm experimentally since pi has infinitely many digits. So there has to be theoretical reason for us to...
You don't need a dictionary to know that, its obvious if you assume everything has a reason. Otherwise you are just suggesting matter was already there without any reason. If you don't believe in causation why do you do science for? You just say "thats the way it is here is the statistics" for...
How can you ever be sure something is probabilistic. Even if you set up the same experiment and get a different result, there is a chance that you are missing some independent variable and the experiments are not the same. Or when you see an electron suddenly do a weird thing, there might be a...
