First ensure that your magnetization direction is set properly in the Material Definition dialog.  
Magnetization direction can be assigned several ways, below are three such approaches. 

1. Editing the existing material property with Z-component Unit Vector assigned as "1", or
2. Cloning an existing material to create a new material, then editing the existing material property to assign the magnetization in the Z-Component, or
3. Using the existing material property (which is default magnetized in the X-direction) and creating a new coordinate system that aligns the x-direction of that coordinate system with the desired magnetization direction.  


The screen capture below, shows option #2 - the new material definition with Z-Component assigned as "1", and "0" for the other Components ...
