AI Thread Summary
To determine the energy required to magnetize soft iron with a small hysteresis loop, one can analyze the material's coercive force and magnetic properties. The relationship between magnetization energy and demagnetization energy is confirmed, suggesting that understanding one can aid in calculating the other. Additionally, applying torque to each magnetic moment in the material may provide insights into the magnetization energy. Exploring these factors can lead to a clearer understanding of the energy dynamics in soft iron. Accurate calculations will ultimately depend on the specific characteristics of the material being studied.

Out of all the formula's I studied, I could not figure out how much energy is required to magnetize soft iron ferromagnetic material that has a small hysteresis loop(Due to the low coercive force)...
How can I figure this out?

Also magnetization energy = demagnetization energy correct?

Maybe I can figure it out from the torque applied on each moment in the material and know the magnetization energy?
 
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...
