Hi i've a big problem with FEMM.
I use FEMM to calculate the effects of magnetic
shield on electrical substation.
First I used a 3 mm alluminum shield and all
it's ok.
Next i used a mumetal shield, but in this case the
shielding effect is less then alluminium shield.
But this result is surely incorrect.
Moreover, in Material Library, mumetal conductivity
is 0, but mumetal conductivity is 1.8. If i use this value, the shieldin geffect
is still less!!!!!!
Why?
Thanks and, please excuse me for my poor
english. |
