Reversing/Weakening a Permanent Magnet's Field: A Mystery?

Click For Summary
SUMMARY

This discussion centers on the potential methods for reversing or weakening the magnetic field of a permanent magnet. It references the use of coiled wire wrapped around the magnet as a technique to reverse its poles, although it lacks detailed information on temporarily altering the magnetic field. The concept of coercivity is mentioned as a key factor in the permanent magnetization process. Additionally, an old-fashioned soldering gun is suggested as a tool that can reverse a hand compass, emphasizing the experimental approach to understanding magnetism.

PREREQUISITES
  • Understanding of permanent magnet properties and coercivity
  • Familiarity with electromagnetism principles
  • Basic knowledge of electrical circuits and coiling techniques

Found one article saying it is possible to reverse poles of permenant magnet using coiled wire wrapped around magnet, but nothing about the possibility of temporarily reversing or even temporarily weakening the magnetic field.. if there are any magnetism connoisseurs out there..

That's how the magnet factory in my town makes them permanently magnetized.

An old fashioned soldering gun will reverse a hand compass.

Try it. One experiment is worth a thousand expert opinions.
