Dynamic Relative magnetic permeability

Click For Summary

Discussion Overview

The discussion centers around the inquiry into materials or methods that allow for the instantaneous, continuous, and periodic variation of relative magnetic permeability (μr). Participants explore potential applications and technical resources related to this topic.

Discussion Character

  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant asks about materials or methods for varying μr and requests references for further information.
  • Another participant suggests using a traditional Magnetic Amplifier to achieve the modulation of μr by varying the saturation level of the magnetic material.
  • A follow-up request for technical information on Magnetic Amplifiers includes inquiries about working principles and graphs relating μr to time and current.
  • One participant recommends starting with the Wikipedia page on Magnetic Amplifiers and exploring additional resources linked from there.

Areas of Agreement / Disagreement

Participants generally agree on the potential use of Magnetic Amplifiers for varying μr, but the discussion remains open regarding specific methods and resources.

Contextual Notes

The discussion does not resolve the specifics of the materials or methods for varying μr, nor does it clarify the technical details of Magnetic Amplifiers beyond initial suggestions.

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:
