Magnetic Field Source

["tano1938" <rgarritano@xxxxxxxxxxx>]

I'm a first time user of femm. I've been working through the 
tutorial and am confused by the units and significance of 
the "Magnetic Field Source", i.e. Weber/meter. How does it relate to 
Magetic Intensity (H) or Flux Density (B). Since it is a user input, 
I'd like to know how to apply it to a practical situation. I've 
never had to use it before, but I've never used an FEA program before 
also.

Thanks for your help.
