Question

hello, this is electromagnetics class

I want to help me with all of these five questions please with a clear picture and step and clear written.

thank you

Shown in the figure is a "partial circular loop" of radius e that sits in the z-h plane. The loop carries a known curent and starts at an angle (20) and ends at an /2.-3/2, and the observation point for the magnetic field H is at the origin. This description is for (52) For the questions tha follow, asume that e3, h-2, angle questions I through 5. 1. What is the position vector to the source? None of the others b. 3m2 c 3+3+3 d3+(/2) (3r/2) a. -3+2 What is the differential length change element for this current? 2. VIBadeP a. b. 3dpy 3de's c. d. None of the others 3dd+2d e. 3. What is dexR for this problem? 6dd' a. b. 18do-9do' c. None of the others -6de-9de d. e. P6+p9 4. What is H at the origin? None of the others a. 34(13)-9] 314(13)4-3 (13)" 12/.9(3/2)| 314(13) 14+32] b. c. d. e. in the case 5. Based on either intuition or perhaps your answer from question #4, which would you expect to be where the observation point is zh rather than z0 for the magnetic field H? It will be finite at z h and point in the + z direction It will be finite at z h and point in the-z direction true a. b. None of these c. It will maintain a similar direction as in question # 4 at z - h d. It will go to zero at zh and point in the +z direction e.
