1. The problem statement, all variables and given/known data 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. 2. Relevant equations biot-savart law ? 3. 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?
