Main Question or Discussion Point
Hello everyone. I need to simulate flux densities generated by thin films of permanent magnets of varying composition. This is to guide selection of parameters for sputtering of Nd-Fe-B permanent magnets. Does anyone know of a program which will allow me to simulate fields from permanent magnets of an arbitrary geometry? And is there a way to vary the magnetic properties? Basically what I'd like to do is model a process in which sputtering is used to create regions of different magnetic fields by varying the process parameters (ie carrier gas pressure). Thanks for any help anyone can provide.
