Magnet Myths and Misconceptions

@Chris


I'm glad you jumped in with some suggestions and I made some plots which actually surprised me a bit. I didn't realize how far out the polarity transitions from the North face north polarity to the smaller transition to a South polarity on these magnets along the plane of the pole.
As well as didn't expect the result with the hall sensor facing the side of the magnet at the center. I expected some very small deviation however it was zero from the side to 10" out.


Interesting.

Here are the graphs.

Thanks AC!

Clearly graph 2 is showing a reading for a Magnetic Field that is Parallel to the Axis of the Magnetic Field but in reverse! It is also stronger than the Poles? How I wonder? 3.8 --> 4.1 - I am a bit surprised with the result too! Still these changes still prove the Equator is still different to the Poles!

I have to admit defeat here with a Small Magnet, AC has provided enough proof here for me.

Even though other experiments show results that still show a "Difference" from the Poles to the Equator, AC has provided enough proof to say that the Magnetic Field may not be showing these other results. This result is NOT shown in the Iron Filing Experiment or the Compass Experiment!

Even though, all should keep an open mind, no matter what!

Kind Regards

the output of the Hall effect sensor UGN3503UA  shows a dip in the magnetic field near the midpoint of a bar magnet.

Rotate the face of sensor 90deg and it will not.
If you move on a plane perpendicular to the bar and crossing the midpoint of the bar, you will be able to measure the field.

@AC - I don't want to burden you, but do you have say 10 ferrite magnets all the same size?

Thinking about the last result, Magnetic Field Strength 'H' over Distance Travelled, could, like we already predicted, obscure the result and be the reason we can not see what we are looking for.

Thus Science showing the "Long Solenoid" experiment not the "Short Solenoid" experiment!!!

A Keeper will obscure the Magnetic Field. So will very high Magnetic Field Strength!!! N42 Neo is possibly as high as 6000 Gauss depending on the size.

So, to be correct and be properly Scientific, I with-draw my previous statement of defeat because it is still not conclusive even though AC's experiment did show correct result!!!

Its just an obscured Result because of High Field Strength.

Kind Regards
