Evaluating integral for magnetic field intensity using mathematica


Hi, all:

Did anyone try to use Mathematica to calculate the magnetix flux intensity
of a rectangular magnetic block at an arbitrary point xyz?  I am using the
formulat

H = -1/4pi*Integral [n' . M' (r_vector-r'_vector)
da'/(r_vector-r'_vector)^3]

I have seen the result done using mathematica, but when I try to evaluate
this integral on my computer the mathematica has been taking about 4 hours
and still did not produce any results?  Is there a trick to this problem?
