Dynamic Relative magnetic permeability

[djsourabh]

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:

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...
