Keep in-mind that the plot from a hall sensor will not match the output of a coil. Not the waveform, anyway. The upward plot of the hall output will be related to above zero on a voltage output and below zero voltage on the downward swing(of the hall output)( or vise-versa ). The point is.... the passing rotor magnet should not cause a magnetic reversal. Since the rotor magnet magnetic force is roughly the same as either top or bottom stator magnet force, sticking the rotor magnet in between the stator magnets just causes the rotor magnet field to ' flatten ' while both stator fields are shoved up or down, but away. In other words... when the rotor magnet is in between the stator magnets there are two radial fields formed. Those radial fields are polarized at the center and at the periphery of the radial field. It might be interesting to see that with your sensor. The motor doesn't need to turn to see what I described. As for why the Gaussian plot doesn't change with load.... The above statements are already enough to start a post bombing war  Relax. It is the way it should be. it is so nice being able to see the field strength and polarity
My favorite 'bitch'  Even though someone skilled in these arts can safely assume what the magnetic fields are doing, in almost any case, you should never assume. My favorite 'bitch' is that folks speak of magnetic fields and don't even have the proper equipment to measure them. They use a voltage or current probe/connection to measure magnetic fields ? ? ? Of course, we can just take the current and voltage readings and do the math  Fine if you are repairing a power supply or flashlight ('torch' - to you Peterae  ) or something else just as common.
