## What is the magnetic field at the center of an arc of current of radius R?

The arc curves through an angle θ. If the current is counter-clockwise the magnetic field at the center is out of the page.

The magnetic field dB from a representative piece of the wire is:
dB = μo I dl /4π r^2

Our integral for the net field is easy:
B =μo I/4π R2 ∫ dl
B = μo I s/4π R2

where s is the arc length, equal to Rθ.
Therefore B =μo I θ/4π R
