Question
In Fig. 29-38, two circular arcs have radii a = 13.1 cm and b = 10.6 cm, subtend angle ? = 75.0?, carry current i = 0.343 A, and share the same center of curvature P. What are the (a) magnitude and (b) direction (answer in or out to mean into or out of the plane of the figure) of the net magnetic field at P?
In Fig. 29-38, two circular arcs have radii a = 13.1 cm and b = 10.6 cm, subtend angle ? = 75.0?, carry current i = 0.343 A, and share the same center of curvature P. What are the (a) magnitude and (b) direction (answer in or out to mean into or out of the plane of the figure) of the net magnetic field at P?Explanation / Answer
B = oi/2R
Net B = 1.26*10-6*0.343*( 1/(2*0.106) - 1/(2*0.131)) *(75/360)
B = 8.15 *10-8 T
direction is out of plane
