SUMMARY

This discussion focuses on calculating the magnetic field (B) and magnetic field intensity (H) along the axis of a uniformly magnetized finite cylinder. Two methods are proposed: using magnetization currents and considering magnetic charges. The comparison to a finite solenoid is questioned, and clarification on the concept of magnetic charges, specifically magnetic monopoles, is sought. The discussion emphasizes the importance of understanding these concepts in magnetostatics.

PREREQUISITES
  • Understanding of magnetostatics principles
  • Familiarity with magnetic field concepts (B and H)
  • Knowledge of magnetization currents
  • Basic grasp of magnetic monopoles and their theoretical implications
NEXT STEPS
  • Study the derivation of magnetic fields in uniformly magnetized materials
  • Learn about the application of magnetization currents in magnetostatics
  • Research the concept of magnetic monopoles and their role in theoretical physics
  • Explore the similarities and differences between finite solenoids and uniformly magnetized cylinders
USEFUL FOR

Students and professionals in physics, particularly those specializing in electromagnetism and magnetostatics, as well as engineers working with magnetic materials.

Dear friends,

I'm having trouble with this magnetostatics problem.

I have a uniformely magnetised finite cylinder and I'm asked to find B and H along the axis, using two different methods to get the correct answer.I believe the first one is considering magnetisation currents and the other one "magnetic charges".

I don't know if I'm doing it right when I compare this problem to the one of the finite solenoid (is it the same). What are magnetic charges?

Thanks for your help

I assume "magnetic charges" is referring to the magnetic monolpole. Not sure what you will do with it, but by analogy to electric charges and polarization of dielectrics there should be a representation of magnetic dipoles as combinations of two magnetic monopoles
