Current creates magnetic fields (Biot-Savart) Current travels clockwise in the loop of wire shown below, and you are interested in the magnetic field at the indicated location. You approximate the loop with six segments. The following questions are one way to get a rough estimate of the direction of the magnetic field. X 3 4 2 5 1 6 (a) Rank the magnitude of the magnetic field contributed by each segment from largest to smallest. If some of the segments seem like they might contribute similar-magnitude magnetic fields, indicate that they're similar and briefly explain why. (b) What is the direction of the magnetic field due to the segment with the largest contribution?
