Magnetic Susceptibility VS. Relative Permeability

AI Thread Summary
Magnetic susceptibility and relative permeability are distinct but related concepts in magnetism. Magnetic susceptibility measures how much a material will become magnetized in an external magnetic field, while relative permeability indicates how much a material can enhance the magnetic field compared to a vacuum. Both properties are crucial in applications like transformer cores, magnetic shielding, and inductors. Understanding these differences helps in selecting materials for specific magnetic applications. Clear differentiation between the two is essential for effective use in engineering and physics.

What is the difference between the two and what are the applications of them in a magnetic material?
 
Physics news on Phys.org
Presumably you have looked up the definitions of the terms ... the same sources should provide examples.
So what is the problem?

(note: sounds like the sort of question that gets asked for homework).
 
I have and the explanations of the two have confused me. To me they both sound like the samething. Can you give me a clear explanation of the two?
 
One is to do with magnets, and the other to do with magnetic fields.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
