Discussion Overview

The discussion focuses on the formation of magnetic field lines between two pairs of magnetic dipoles arranged in a specific configuration. Participants explore the effects of distance and orientation of the magnets on the resulting magnetic field, considering both theoretical and practical implications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant inquires about how magnetic field lines are formed between two pairs of magnets, specifically with one pair oriented NS and the other SN, and the implications of their distances on field strength.
  • Another participant interprets the configuration and suggests that the orientation of the magnets is crucial for understanding the field lines, noting that the back pair's orientation is unclear.
  • There is a suggestion that if all magnets are of equal strength, the magnetic flux from one pair may not significantly interact with the other pair due to their relative distances.
  • A participant proposes using vector potential to analyze the field due to the four dipoles, indicating a more complex approach may be necessary for complicated configurations.
  • One participant expresses the belief that the main field lines would primarily be between the slabs of each pair, given their closer proximity compared to the distance between pairs.
  • There is a request for clearer diagrams to better illustrate the configuration and movement of the magnets, emphasizing the importance of orientation and distance in understanding the magnetic interactions.

Areas of Agreement / Disagreement

Participants express differing views on the interactions between the magnetic pairs, particularly regarding the significance of distance and orientation. There is no consensus on the exact nature of the magnetic field lines or their interactions.

Contextual Notes

Participants note the importance of relative separations and orientations of the magnets, but there are unresolved aspects regarding the dimensions of the magnets and the specifics of their arrangement.

Hi , I am interested to know how would the magnetic field lines be formed and what effect each one of them would have to the one next to the other in such a configuration. I have two pairs of magnets.

Distance between each magnet in a pair , numbered 2, is 2 mm. the distance between the two pairs of magnets , numbered 1 is 1cm.

In one pair the magnets stand NS in the other they are opposite SN, this is not a homework I was just interested what happens in such a configuration , if the distance between opposite magnets in a pair is smaller than that of the same opposite magnets between the pairs do most strength of field goes between the pair or is it shared also with the side pair even though it is further? I hope you understand my question , thank you :)

If I understand that diagram correctly, you mean that the poles are on the large faces of the slabs - which are supposed to represent permanent magnets.

The front pair are oriented with S (left) and N (right) poles facing the front.
I cannot tell what the orientation of the back pair is supposed to be from the diagram.
From your description, the back pair are N (left) and S (right) poles facing front.

If you draw the situation from overhead, you should be able to sketch in the field line following the usual rules.
If all magnets are equal strength, then don't expect flux from back left N pole to attach the front right S pole.

Relative separations would be important but I cannot see any magnet dimensions.
For complicated configurations of magnets, I'd usually want to go to the vector potential.
You can always just add the fields due to four dipoles?

The effect, when released, is that the magnets will rotate and come together in a heap.
 
Hi Simon , well , I edited the picture for better understanding , the magnet pairs are the ones colored with similar color dots on their sides.the so called poles are the inner faces of the magnet slabs. the ones who face each other.

Now the magnet slabs are not loose they are attached to a armature so to speak of.the distance number 2. is smaller than the distance number 1. also the distance number 1. is the distance between the two pairs of magnets not distance number 2.

Especially if the magnetized parts are the ones facing each other in the pairs , I think the main field lines would be between each opf the two slabs in a pair right?

Please redraw the picture from overhead as advised.
Show the "armature" and any freedom of movement - pivots or whatever.

Please make the orientation of the magnets clear - you have seen enough diagrams of magnets online to know what is needed.
