A conductor consists of a circular loop of radius
R = 14.4 cm
and two long, straight sections as shown in the figure. The wire lies in the plane of the paper and carries a current
I = 1.60 A.
Find the magnetic field at the center of the loop.
The Attempt at a Solution
I know I need use biot-savart law to get the field created by the loop, which is giving me 8.77 uT. This is apparently within 10% of the correct answer.
Do i need to find the current from the straight part of the wire too (superposition)?
I'm just not sure how to do this / what equations to use to do this?
