AI Thread Summary
FEMM software can be used to calculate magnetic field energy, but users may encounter issues with consistent energy readings. The energy calculated may not change when selecting different surfaces, leading to confusion about the software's functionality. To analyze energy interactions between magnets and ferromagnetic materials, understanding how magnetic domains realign is crucial. Additionally, when two magnetic fields overlap, their interaction can either increase or decrease energy, depending on their alignment. Seeking guidance on specific FEMM functionalities and calculations is recommended for accurate results.

Hello,

(I'm not fluently in english, sorry if it's not a pure english)

I use FEMM software for caculate energy. I have found an integral fonction "Magnetic field Energy" when I select a surface. But I have always the same energy, I don't know why. Is there necessary to make something special ?

In fact, I would like to calculate the energy when a magnet draw a solid metal, or when a magnet draw another magnet. It's a simple problem.

The potential energy move between a solo magnet or a magnet with metal, no ?


Somebody can help me ?

Thanks

Ludovic

When a magnet pulls a ferromagnetic metal it actually realigns the magnetic domains in the metal so that they form a magnet. That said, there is a specific http://hyperphysics.phy-astr.gsu.edu/hbase/electric/engfie.html" . When two fields overlap they will superimpose to either make the field stronger (increasing the energy and requiring work) or weaker (reducing the energy and doing work).

good, thanks, but how can I use FEMM software for have energy in the magnet ?
 
I have no idea. I don't even know what FEMM software is.
 
does anybody can help me ?
 

Thread 'How to picture the vector potential?'

Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
