Differences between Electromagnetic flux and magnetic flux

Click For Summary
SUMMARY

Electromagnetic flux is not a distinct concept; it is synonymous with magnetic flux, particularly in the context of electromagnets. In permanent magnet machines, the magnetic flux is the primary focus, as it interacts with the stator cores, which may contain copper wires. For effective magnetic flux shielding in large stator cores, materials such as soft iron are recommended, especially for high magnetic fields exceeding a few Gauss.

PREREQUISITES
  • Understanding of magnetic flux and its properties
  • Familiarity with electromagnetism principles
  • Knowledge of materials used for magnetic shielding
  • Basic concepts of stator design in electrical machines
NEXT STEPS
  • Research the properties of soft iron for magnetic shielding
  • Explore the design principles of permanent magnet machines
  • Learn about the effects of magnetic flux on stator cores
  • Investigate materials suitable for high magnetic field applications
USEFUL FOR

Electrical engineers, materials scientists, and anyone involved in the design and optimization of magnetic systems and permanent magnet machines.

May I know that are there any different between the electromagnetic flux and magnetic flux?

Are there any electromagnetic flux in a permanent magnet machine?

What kind of flux will go through the permanent magnet machine's stator cores with copper wires on it?

I am really sorry to ask so many questions in one go. However, I really need help to make myself clear on this concept.

Thank you in advance for the helping!

hi vunteng! welcome to pf! :smile:

i've never heard of electromagnetic flux :confused:

the flux from an electromagnet (or any other magnet) is ordinary magnetic flux

where did you see "electromagnetic flux"?​
 
Actually I am looking for a material which is magnetic flux shielding. It is to hold the large size of stator core which around 1m long and 0.2m wide, so it must me very strong and magnetic flux shielded.

Can you please suggest me few materials in the above properties?
 
For high magnetic fields (above a few Gauss), boxes made of soft iron are good. Remember that H-parallel (tangential component of H) is continuous across an air-iron boundary. See picture of clock in
