Edge/Surface Force Density Calculation in 2D by Field Calculator for Permanent Magnets.
Hi dear friends,
Nowadays i am working on the analysis of attraction force between 2 permanent magnets.
Structure is simple and consists only 2 permanent magnets in air with same direction magnetization.
My first thought is to check the results in 2D FEM and analytically.
The results i met in 2D and the analytical calculations by hand are both similar so no doubt.
Also the result by field calculator by taking line integral of Edge Force Density over the magnet and multiply with depth also give right solution.
But i have problem to calculate Edge and Surface Force Density by field calculator.
I make the calculations in field calculator based the equation on the picture1 but results are so different .
Then i tried to make calculation based on as in picture2 but no success.
Can you pls share your kind experience how to calculate Edge and Surface Force Density by field calculator in 2D for reluctance type forces as in attraction force between permanent magnets.
