Magnet Myths and Misconceptions

@AC - Also can you please post the Length of the Magnet?

Thank You!

1: Orthogonal to the Magnetic Axis to the Magnetic Axis from the North Pole Plane.2: Parallel to the Bloch Wall but still Orthogonal to the Magnetic Axis. At the approximate centre point of the Poles.3: Orthogonal to the Magnetic Axis from the South Pole Plane.

By " Orthogonal to the Magnetic Axis to the Magnetic Axis from the North Pole Plane" I assume you mean the hall sensor face is perpendicular/ortho to the N-S vertical axis moving along the north pole plane or across the North face of the magnet.


1)The hall sensor face is ortho to NS axis, NS axis vertical,  moving along North pole horizontal pole plane across the North pole face.
2)The hall sensor face is ortho to NS axis, the NS axis vertical , hall face pointing towards magnet side in center of magnet registers zero change, no picture because change is zero..
3)The hall sensor face is ortho to NS axis, NS axis vertical, moving along South pole horizontal pole plane across the South pole face.


The last plot was interesting, hall sensor face parallel with NS axis moving from 6" away towards the North pole face along the North pole plane then past it 6". The South polarity peaks about 1.5" away from the face then transitions to North polarity at the North face and once again transitions to a south polarity peaking 1.5" away.


It helps if you could describe the hall sensor face orientation in relation to the magnet NS axis or other descriptor and a specific start/end point along with the direction of travel. I should note that when I say hall sensor face parallel to NS axis I mean the sensor face is pointing along the same axis as the NS axis drawing an imaginary line through the sensor face.

Hi AC,

Did I post my Picture n time? Sorry I thought about a Picture after I had already posted this request. Where the direction of detection is the same for all movements. Detection of the Hall Sensor Face is detecting in the direction of the Arrow.

Can you confirm the Picture and the experiment match?

Thanks AC!

Kind Regards

Much better description, will take measurements.
