Calculating flux density around a conductor

[silverslith]

Can anyone tell me how to calculate the flux density at a distance from a current carrying conductor? In a vacuum would be fine. I understand its an inverse law for a conductor of infinite length. Infinite length is an acceptable assumption, I'm only after ballpark figures.:)

seems like what I'm looking for but don't have a subscription.:lol:

Magnetic flux? Why not use ampere's law?

 

[math]

\int B\cdot ds = \frac{4\pi}{c} I_{enclosed}

[/math]

 

So if you know the current, you can get a pretty good estimate of the magnetic field/magnetic flux.
