Why Isn't a Lone Proton Considered a Magnetic Monopole?

Click For Summary
SUMMARY

A lone proton is classified as an electric monopole due to its positive charge, but it is not considered a magnetic monopole. Protons exhibit magnetic dipole characteristics, meaning they possess a north and south pole, which leads to magnetic interactions based on their orientation. The discussion clarifies that protons do not repel magnetically; instead, their magnetic behavior is similar to that of macroscopic magnets, where attraction or repulsion is determined by the alignment of their dipole moments.

PREREQUISITES
  • Understanding of electric and magnetic monopoles
  • Basic knowledge of magnetic dipoles
  • Familiarity with the properties of protons
  • Concept of magnetic interactions and orientation
NEXT STEPS
  • Research the properties of magnetic dipoles in quantum mechanics
  • Explore the concept of magnetic monopoles in theoretical physics
  • Study the behavior of protons in magnetic fields
  • Learn about macroscopic magnetism and its principles
USEFUL FOR

Students of physics, educators explaining electromagnetic theory, and researchers interested in particle physics and magnetism.

Simple question. Why isn't a lone proton with no electrons considered a monopole?
 
Physics news on Phys.org
It is an electric monopole, not a magnetic one.

And protons repel magnetically?
 
Protons are magnetic dipoles. Whether they repel or attract due to the dipole moment depends on their relative orientation, just as for macroscopic magnets.
 
Ok that makes sense now. Thank you!
