Integrate Biot & Savart law.

anonymous · Answer

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

anonymous · Answer

How about a conductor of finite size?

anonymous · Answer

Integrate this vector expresion

anonymous · Answer

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 $$B=\mu0I/2\Pi r$$

anonymous · Answer

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

anonymous · Answer

I am asking for finite length..

then magnetic field at point p is given by$$B = \mu o I/4 \pi r ( \sin a + \sin b )$$
