The ratio of mutual flux to primary flux is the same as the coefficient of coupling. However, the flux linkage of the secondary is the mutual flux multiplied by the number of turns of the secondary. Therefore the flux linkage ratio is not the same as the coefficient of coupling and may have a value greater than 1 unlike the coefficient of coupling which is ...

So first off this becomes a lot easier to visualize how it behaves if you just rotate the image a bit like this: We can now see that for the majority of length of the TL the two wires are balanced and equivalent with each other. It is only at the very end where one wire is a bit longer and sticks out without matching component on the + end. This makes sense ...

Most signal generators have a default output impedance of 50 ohms so, if you recalculate current through the load resistor based on it actually being 62 ohms, you are a lot closer to measuring the proper B theoretical value implied by the H field.

In the case of capacitive coupling, the mechanism is the change in an electric field perpendicular to the conductors, so there's no reason the resulting current would not flow in both directions. In the case of inductive coupling, the mechanism is the change in a magnetic field wrapping around the conductors. The direction of wrapping of a magnetic field ...

Because waves have a length to them and physically move through the medium. In an ideal feedline you would have 360 degrees of phase for every wavelength of distance (since it will go through a full cycle in that space). If it helps try to visualize water waves. If a water wave is coming towards you and you happen to be at the peak of the wave at the ocean ...

So why does the angle of the reflection coefficient depend on where you are on the T line? Because the reflected wave is still produced at the same location (call it x = 0), and then travels back to wherever you're measuring the reflection. As it travels, it accumulates phase.
