Percentage of external B field absorbed by inductor?

Click For Summary
SUMMARY

The discussion centers on calculating the percentage of an external magnetic field absorbed by an inductor, specifically when a magnetic field source is positioned at point A and the inductor is at point B. The formula for energy in an inductor, E = 0.5 LI², is mentioned, but the focus is on determining the attenuation of the magnetic field due to the solenoid. Participants suggest using numerical analysis software like ANSYS to model the magnetic field interactions and provide a more accurate calculation of the field deflection caused by the inductor core.

PREREQUISITES
  • Understanding of magnetic fields and inductors
  • Familiarity with the formula for energy in inductors (E = 0.5 LI²)
  • Basic knowledge of numerical analysis techniques
  • Experience with simulation software, particularly ANSYS
NEXT STEPS
  • Research how to use ANSYS for magnetic field simulations
  • Study the principles of magnetic field attenuation in solenoids
  • Explore numerical methods for analyzing magnetic field interactions
  • Learn about the properties of ferrous materials and their effects on magnetic fields
USEFUL FOR

Students in electrical engineering, researchers in magnetic field analysis, and professionals involved in designing inductors or magnetic systems will benefit from this discussion.

Hey all, if a magnetic field source is at A and an inductor is at B halfway from C, the measuring point will the field be attenuated and decrease in strength due to a percentage of it being absorbed by a solenoid if so how would one calculate the amount, I found how to calculate energy in an inductor E = 0.5 LI^2 from integrating power equation but not any information on my specific problem. Any help appreciated,

A diagram would help.

If you want to figure out how the B-field is deflected by the presence of a piece of ferrous metal (the inductor core), then the way you figure that out is with a numerical analysis software package like ANSYS or similar software. Does that make sense? Are you a student at a university? You may be eligible to use a low-cost version of that type of software if you are a full-time student...
