Discussion Overview

The discussion revolves around methods to weaken the magnetic attraction between two magnets after they have already been attracted to each other. Participants explore various approaches to achieve this without altering temperature, using stronger magnets, or employing chemicals. The conversation includes considerations of shape, speed, and the use of materials with specific properties.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant inquires whether the shape of the magnets could influence the strength of the magnetic attraction when attempting to separate them.
  • Another participant suggests that the speed at which the magnets are pulled apart might affect the separation process, questioning if a quick yank versus a slow pull would make a difference.
  • A third participant proposes that inserting a material with high magnetic permeability could redirect magnetic field lines, potentially weakening the attraction, though this would require mechanical energy similar to that needed for direct separation.
  • Additionally, the use of electromagnetics is mentioned, where reducing the current could weaken the magnetic pull.
  • One participant describes a scenario involving three magnets, questioning if it is possible to manipulate the forces involved to achieve separation without equalizing the forces acting on the magnets.

Areas of Agreement / Disagreement

Participants express various ideas and hypotheses, but no consensus is reached on a specific method to weaken the magnetic pull. Multiple competing views and approaches remain under consideration.

Contextual Notes

The discussion does not resolve the assumptions regarding the effectiveness of different methods proposed, nor does it clarify the specific conditions under which these methods might work.

I have a question regarding magnetic pull. Is there anyway that a magnet can be attracted to its optimal pull to another magnet and then weakened for separation in any way? So basically I'm wanting to know how to weaken the magnetic attraction force once the magnets have attracted (without temperature change or without attraction to a stronger magnet or without any other chemicals). Could the shape be an influence?
 
Physics news on Phys.org
could the speed of the pull be an infuence? I mean if I yank it instead of slowly pull it would that matter (if the forces were the same). Any ideas?
 
You can redirect the magnetic field lines by insertion of a material with high magnetic permeability, and of suitable shape.

This will take mechanical energy to accomplish ... approximately the same as required to separate the magnets directly.

Alternatively, you can use electromagnetics and simply reduce the current.

I need it to be weaker. Basically what I'm trying to accomplish is:
Magnet A is attracted to magnet B
I get Magnet C to attract to Magnet B, therefore moving it away from magnet A (magnet C has a higher magnetic field/attraction than Magnet A hence, the pull away)
Now, I want Magnet C to pull away from Magnet B. To do this I have the same pull/attraction power Magnet A would've had to Magnet B (pull power = Magnet C moving horizontally) and gravity. Could I get anything shape/speed etc using the same amount of force to move this away or would it be a case of equalisation.

Does the above make sense lol.
