Question 1

a. Imagine a strange current loop. The current I flows in the direction indicated in a loop lying in the x-y plane as shown. You should put the origin of your system from coordinates at the center of the partial circle. In this case, the segment lies at ( = 2) and (2 < < +2). Use the Biot-Savart law to determine the magnetic flux density at center of the circle. Remember that you can consider each of the segments separately. b. If the radius of the circular portion is R = 2 cm and the current in the loop is 5 A, find the magnitude of the field at the center of the loop. Do not forget the units.

Question 2

Consider a triangular loop with a current = 0.5 through it. The corners of this triangle are at coordinates (0,-1,0), (0,1,0) and (0,0,3). The direction of the current is such that it moves in the same order as the given list of coordinates. Determine the field at the origin.
