Expression for Biot Savart...

Please login with a confirmed email address before reporting spam

hi,
I am doing point evaluation to compute magnetic flux density at a point using biot savart law. I am working in the magnetic and electric interface (AC/DC module). The conductor is lying along x-axis. The expression that i used to compute 'B' is ''mu/(4*pi)*int(mef.Jx*(ra)/(r)^3)'' where ra is the vector and r is its magnitude. Could anybody help me whether my expression is right or wrong. It is giving me value but when i change the point it is giving me the same value that is why i am in doubt....
