MY NOTES ASK YOUR TEACHER A thin conducting wire is bent Into the shape shown in the figure. The circular portion of the wire has radius 30.0 cm. The wire is in the plane of the screen and carries a current 1.70 A. What is the magnetic field at the center of the loop? (Give the select the direction from the options provided.) magnitude stal magnetic field as the superposition of the field due to the long straight wire and that due to the circular loop. Find the sum of these contributions. IT direction into the screen VV Need Help? Rand It
