The magnetic field due dB due to an element dL carrying a steady current I at a point P at a distance r from the current element is \[dB=(\mu0/4\pi) I *((dL*r)/r ^{3}))\]

There is another one...The magnitude of the mag field at a distance R from a long straight wire carrying a current I is given by \[B=\mu0I/2\Pi r\]

But this is the result for a wire of infinite length..
