    Curve Loop
AI Thread Summary
The saturation field on a Hysteresis Loop is identified where the curve levels out, indicating that further increases in the magnetic field do not significantly increase magnetization. The initial relative permeability is determined by the slope of the curve at the origin, calculated by dividing by mu0 in SI units. The maximum relative permeability is defined as the maximum slope of the B versus H curve. It is not infinite, as it represents a specific value at which the material's response to the magnetic field is at its peak. Understanding these concepts is crucial for analyzing magnetic materials effectively.

Ok. I am having trouble identifing the saturatoin field on the Hysteresis Loop. How do I find it?Also the initial and maximum relative permeability. Is the maximum relative permeability infinte?

The "saturation field" is the field at which the curve just about levels out.
The initial relative permeablilty is the slope (divided by mu0 in SI units)
at the origin for H starting from zero.
The max RP is the max slope of the B vs H curve.
 

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'

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...
