You now need \[B = \frac{\mu_{o} I}{2 \pi r} \] where r is the distance from the wire.

For the last part you can look at this: http://hyperphysics.phyastr.gsu.edu/hbase/magnetic/wirfor.html#c1 (this website is great for looking things up, though the correct page is usually easiest to find using the method of searching google for "#what you want# hyperphysics"
