Magneto Static : solved equations (vector potential 3D)
Introduction
The magnetic vector potential is a proposed model for 3D applications.
This model can be used by :
- The 3D solver of Flux 3D.
Equation solved with magnetic vector potential model (3D)
The equation solved by the finite elements method in a Magneto Static application is written:
Where:
[νr] is the tensor of the reluctivity of the medium (in m/H)
ν0 is the magnetic reluctivity of the vacuum ; ν0 = 1/μ0 = 1/(4 π 10-7) (in m/H)
is the magnetic vector potential (in Wb/m)
is the source electric vector potential source (in A/m)
is the source magnetic vector potential (in Wb/m)
is the induction of the magnets (in Wb/m)
