Thank you vanhees71. I cannot understand how the hall effect is relevant :-(. As for the relativistic treatment you say that does not apply on this paradigm. However I will read and try to understand :-) your essay as soon as I get some time.
I still cannot understand where the energy and the...
A) I do not know
B)yes and I forgot to mention the added magnetic field of the rails(as a current flows in them) . I think we have to take account for this too in order to calculate the induced voltage on the loop.
C) on the right side of the rod are static rails. Inside the rails there is...
A) F=T=constant
B) hysterisis due to deformation? Not distinguishable as long as Fdeformation=constant
As per op he talked about heat so the gross simplification is to accept only friction like forces. If he chooses to be fine with constant deformation force (at the same direction of the...
A gross simplification I think is to theoryticaly accept a time duration of the collision. Then take into account the third law, the deceleration of the bullet and the acceleration of the target until they have common speed. If you accept only friction like forces you can calculate the work done...
What berkeman said is right.
If it is for a practical application beware of the maximum charge and discharge current for the specific capacitor you buy.
A "spin off" question:
In these types of problems when there is a closed circuit and a current flows due to the induced emf in the loop if this current creates a secondary magnetic field comparable in magnitude to the initially applied field do we have the right to not take this into account...
Thank you for your reply. It has nothing to do with homework that's why I posted here. Hopefully, I haven't made a mistake.
The attachment you provide do not link anywhere. What I meant was the same figure of the linked post with R=0
The solution with the nonzero R is trivial:
"Induced emf=Bul...
Hello to all. Second post here so I apologise if I post to the wrong place with wrong altitude etc
We have a schematic of a problem like here:

The conducting rod ab shown in the...
Thank you.
English to Greek translation holds for:
Electromagnetic spectrum
Fourier spectrum
Energy spectrum
Mass spectrum etc with the same meaning to both languages.
The Greek word for all these is phasma either ilektromagnitiko, energeias, mazas etc
It seems that the term magnetic spectrum =...
Thank you for your interest
I used to refer this as the "image of the magnetic field lines" to my students translated of course in greek and not as the "magnetic spectrum" as it is referred in the Greek textbook.
I expressed the same question to a Greek forum attended by many Greek teachers...
Hello to all. This is my first post. I hope here is the right place to post.
In a Greek secondary school book I found the term "magnetic spectrum" as the definition of the picture one get when we visualise the magnetic field. There is even a Greek Wikipedia page that I believe it comes from the...
