Dynamic Relative magnetic permeability

AI Thread Summary
Materials and methods for varying relative magnetic permeability (μr) include the use of magnetic amplifiers, which modulate μr by adjusting the saturation levels of magnetic materials. For detailed technical information, resources such as Wikipedia and related links are recommended for understanding the working principles and graphs of μr versus time and current. The discussion emphasizes the importance of selecting the right approach based on specific applications. Users are encouraged to explore visual resources to enhance their understanding. The magnetic amplifier concept is highlighted as a viable solution for achieving dynamic changes in μr.

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... :smile:
 

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
