How to create monopole magnetic material?

Click For Summary
SUMMARY

The forum discussion centers on the experimental creation of monopole magnetic materials by Thinh Nghiem. Two primary methods were proposed: welding two magnets with like poles together and magnetizing a steel specimen using two magnets of the same pole. Testing results indicated that while some samples exhibited monopole characteristics, the majority reverted to dipole status after a short period. The discussion also highlighted skepticism regarding the feasibility of creating true monopoles, referencing Maxwell's equations and the inherent nature of magnetic fields.

PREREQUISITES
  • Understanding of Maxwell's equations, particularly divergence B = 0
  • Basic knowledge of magnetic properties and dipole behavior
  • Familiarity with experimental methods in magnetism
  • Experience with magnetic field visualization techniques
NEXT STEPS
  • Research Maxwell's equations and their implications on magnetic monopoles
  • Explore methods for visualizing magnetic fields, such as using iron filings or Hall effect sensors
  • Investigate the properties of materials that can be magnetized, focusing on ferromagnetic materials
  • Study existing literature on magnetic monopoles and their theoretical applications in technology
USEFUL FOR

Researchers, physicists, and engineers interested in magnetism, experimental physics, and the theoretical implications of magnetic monopoles in technology and materials science.

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...
