3D: Remanent flux density as a function of coordinate X across a material?

I would like to create a material with a remanent flux density as a function of the X coordinate in Cartesian coordinates. How do I do this?

I have tried on 'Edit Material' changing the Magnetic Property to 'Spatial Linear Magnet' but it does not recognise the coordinate X or x as a parameter when I enter the function I would like to use into 'Spatial remanent flux density'.

I would like to use Br = -2*X+1.

 

Thanks!

    Hi,

    You can create a new material type “linear magnet described by Cartesian vector Br”. To do it:

    • General data >> select physics >> select material
    • Right click >> select new
    • A window opens
    • Select magnetic property >> select “linear magnet described by Cartesian vector Br”
    • You have the possibility to put different value of remanent flux density as function of each coordinate.

    In your case, the remanent flux density of magnet is variable along the x axis you can use material type “linear magnet described by the module of Br”. To use the formula: Br=-2*x+1, you need to create an I/O parameter for X. once your parameter is created, you need to create the material type ““linear magnet described by the module of Br” following the step described before. In the the tab “remanent flux density” you put the formula: Br=-2*x+1.

    Hope this will help.

    Best regards.
