Sid786 3 years ago How to determine the magnetic field due to a straight current-carrying conductor of finite size?

• This Question is Open
1. Vincent-Lyon.Fr

Integrate Biot & Savart law.

2. Krishnadas

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

3. Sid786

How about a conductor of finite size?

4. Krishnadas

Integrate this vector expresion

5. Krishnadas

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 $B=\mu0I/2\Pi r$

6. Sid786

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

7. Sid786

I am asking for finite length..

8. Mashy

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