Ok,
Please correct me if I'm wrong;
Flux lines are a sort of mathematical visualisation of magnetic fields, they do not exist. As such, there still exists a magnetic field between flux lines (?), just in calculations we use flux lines because they are simpler (?). In voltage transformers, we use an iron core because flux travels better in iron than air (if this is true, why is this?). Also, since flux lines (i.e. magnetic field) can still exist in air, we can have a transformer without an iron core...? (just won't work as efficiently?).
If the above is correct then I have some doubts;
What does 1 line of flux represent exactly? Is it arbitrarily chosen at point of calculation or it means something? An amount of magnetic field strength or something along those lines? If it is set, then I'd like to know who set it?
Then lastly, I'd like to know how exactly does magnetic induction work? This is what I understand and please correct me if I'm wrong;
A magnetic field passes through a piece of electrical wire, the charged particles (another doubt, the charged particles are just electrons--> right?) in the wire move to minimize the effect of the magnetic field (like magnetisation?) and this is why if you have a DC input to a transformer, you get a jump in voltage when you initially turn it on then goes to zero? (I am not sure about this too, does this happen?). And this is why if you have AC input to a transformer, you get an AC output because the magnetic field keeps reversing and the charges keep going back and forth?
Many thanks for reading, I would greatly appreciate if you would answer my questions. These few fundamental questions have been bugging me for far too long, I have tried researching the answers to these but can't seem to find a black and white answer from anywhere as such I felt it would be best to just ask.
Thanks again...
