Let me name the question of Hall probe question as 9702_w12_q43_q5 and the question of the copper wire moving through the magnetic field as 9702_w10_q43_q5.
The coil that I referred to in post #16 to describe the situation in 9702_w10_q43_q5 is NOT really the small coil that was mentioned in 9702_w12_q43_q5. In post #16, I use the word “look” with “”.
The Fig (a) and Fig (b) in post #16 shows the position of the coil at two different times. Fig (a) is at an earlier time and Fig (b) in the later time to illustrate a coil entering the uniform magnetic field which “looks” like the situation in 9702_w10_q43_q5.
IMO, it is meaningless to talk about the coil moving through uniform magnetic field in 9702_w10_q43_q5.
I am not sure what are you trying to confirm the “meaning” of coil entering, leaving and moving through the uniform magnetic field.
Post #18 Fig 1a illustrates a coil just enters a uniform magnetic field from left to right if we consider the sequences of the diagram from top to bottom.
However, the same figure (Post #18 Fig 1a) can also illustrate a coil just leaves the uniform magnetic field from right to left if we consider the sequences of the diagram from bottom to top.
Post #18 Fig 1b illustrates a coil moves through a uniform magnetic field.
