How to create monopole magnetic material?

Click For Summary

Discussion Overview

The discussion revolves around the possibility of creating monopole magnetic materials, exploring both experimental methods and theoretical implications. Participants examine the nature of magnetism, particularly the existence of magnetic monopoles versus dipoles, and share personal experiments related to this topic.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant describes an experiment where they attempt to create a monopole magnetic material by welding two magnets with the same poles together, claiming to observe a magnetic behavior consistent with a monopole.
  • Another participant suggests using iron filings to visualize the magnetic field of the proposed monopole, questioning its actual monopole characteristics.
  • A different viewpoint posits that connecting two magnets in the proposed manner would result in a magnetic quadrupole rather than a monopole.
  • Some participants express skepticism about the feasibility of creating a monopole from dipole magnets, arguing that the arrangement will always yield a quadrupole configuration.
  • One participant acknowledges the potential for their experiments to contribute to engineering applications, though they remain uncertain about the practical value of their findings.
  • Concerns are raised regarding the adequacy of the measurement method (using a compass) for determining the magnetic properties of the samples, suggesting that a more sophisticated approach is needed.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the feasibility of creating monopole magnetic materials. There are multiple competing views regarding the nature of the experiments and the interpretations of the results, with some supporting the possibility of monopoles and others firmly opposing it.

Contextual Notes

Participants note limitations in the experimental methods and measurement techniques, highlighting the potential for confusion in terminology and the need for clearer definitions of magnetic properties.

OK, whatever. I would be willing to bet that you did not actually construct this object apart from drawings on paper that you think works.

And those polar field lines some think are straight are not straight at all.
They eventually curve to the opposite pole.

The reason most iron-filing set-ups appear to show a polar straight line is that the magnetic force at that point is too weak to align the relatively massive iron-filings into a curve.

Well I tried it. I took a 300mm Iron rod and a N42 nib magnet, starting in the center of the rod and switching to the other side, again starting from the center after each stroke. I then brought it proximity to a compass and indeed the north end of the needle pointed to the end of either side of the rod. I also noticed that the south end of the needle pointed to the center of the rod as I was passing it. So, what you have is not a monopole it just has the same pole on each end and the opposite pole in the middle.

about 2nd solution, when you conected to magneteic with north-north, and South - south , infact, you have one magnetic which is weaker than both of first mgnetic because, their magnetic fields destroy each other...
