Question

DIR E CCO LIVE, Occu, acceleration) of the mass. [12] 13. A piece of wire is bent in the shape shown (two 450 cm horizontal section and a semi-circle section with radius 385 cm). Determine the magnetic field (magnitude and direction) at point P, the center of the semicircle. The current i - 9.5 mA. (Hint you need Bio-Savart Law.) If you show your work in an organized and clear manner that I can clearly see that you are working the problem correctly and not just writing from the memory of some problem that was previously worked out, you will get partial credit, depending on how correct you work is

Answer 1

a Given radias of semicircule (0) = 3.85m and current (i = 9.5mA the Blatsavant low $B = ko I SI Sino 47 72 where o is the angle betweech joining the observation point .p. se piece and line So for horizontal lines this angle is o and a respectively so the magnetic field due to horizontal lines at point p is zero- Now for semicircle the angle is 0= 1/2 So 4K 82 SB = Pere de salle taking the integration on both sides J SB = les besse - Now - uaxit x 9.5x10-3 - 4X 3.85 - = 7748X10-10 Tesla this is the magnetic field at point p.
