Dynamic Relative magnetic permeability

Click For Summary
SUMMARY

The discussion centers on the dynamic variation of relative magnetic permeability (μr) using materials and methods such as Magnetic Amplifiers. Participants emphasize the importance of modulating the saturation level of magnetic materials to achieve continuous and periodic changes in μr. For technical information, resources like Wikipedia and related links are recommended for understanding the working principles and graphical representations of μr over time and current.

PREREQUISITES
  • Understanding of magnetic materials and their properties
  • Familiarity with Magnetic Amplifiers and their applications
  • Knowledge of magnetic saturation concepts
  • Basic principles of electromagnetism
NEXT STEPS
  • Research the working principles of Magnetic Amplifiers
  • Explore the relationship between μr, time, and current through graphs
  • Investigate advanced materials that exhibit variable magnetic permeability
  • Review academic papers on dynamic magnetic permeability modulation techniques
USEFUL FOR

Engineers, physicists, and researchers interested in magnetic materials, electromagnetic applications, and those developing technologies that require variable magnetic permeability.

I want to know that are there any materials or methods by which their relative magnetic permeability (μr) be instantaneously,continuously & periodically varied. Kindly provide the reference document/video for the description if possible.

Depending on your application, you could use a traditional Magnetic Amplifier, or something similar:

https://www.google.com/search?hl=en...8.0...0...1ac.1.64.img..0.18.1013._-HV_AC0v5w

The concept is to vary the level of saturation of the magnetic material, which effectively modulates the value of μr.

thank you very much,Sir! I hope to use the magnetic amplifier concept. Do you know where can I get its technical information? like from it's working principle to it's graphs of μr vs time & μr vs current?

I would probably start with the wikipedia page, and follow some of the additional links to other resources... :smile:
