    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 \[dB=(\mu0/4\pi) I *((dL*r)/r ^{3}))\]

    How about a conductor of finite size?

    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..

    |dw:1359312769537:dw| then magnetic field at point p is given by\[B = \mu o I/4 \pi r ( \sin a + \sin b )\]
