Yes, it is. In Flux (2D and 3D) a magnet material with sinusoidal Br can be defined by using spatial quantity.
The procedure to follow is described below:
| 1 | Create new spatial quantity defined as follow:
Name: ex. BR_SPATIAL
Type: spatial formula
Formula: Cos(FK*(Atan2(Y1,X1)-A))*B_R*Vec3(Cos(Atan2(Y1,X1)),Sin(Atan2(Y1,X1)),0) The following spatial quantities should be previously created in the project to use them in the formula above:
A=0 (it allows setting the phases)
FK=360/magnet_segment_presented (ex. 360/180 for ½ cylindrical magnet).
B_R is the remanent induction in (T)
X1= CLCS(COORDSYS_CARTESIAN,1)
Y1= CLCS(COORDSYS_CARTESIAN,2)

| 2 | Create magnet material defined as follow:
Name: ex. MAGNET_SINUS
Magnetic property: Spatial linear magnet
Spatial remanent flux density: BR_SPATIAL
|
|---|
| 3 | Use the created material in the magnet region definition
|
|---|
To check the result, you can display a 2D curve on a path located in the middle of the magnet region.
Note: The curve should be displayed with respect to cylindrical coordinate system. For instance Comp(1,VLCS(COORDSYS_CYL,Br))
