Question

Electric charge corresponds to (position, speed, 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 Biot -Savart Law.) If you show your work in an organized and clear manner that I can clearly see that you are working the problem eorrectly 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

solutions The magnetic field at Point p due to two straight current carrying wires coi'll be zero. Beacause the point p lies on the Center as the wire. And the magnetic field at Point P due to semicircular carrent = B = x z elo i = 4TX107 9.5X103 4 3.85 = 7,748 x10-10 Tesla, so total field at Point P = B = 7,748 X 1010 Tesla, and this field is directed into the page magnitace = 7.748x10 to JT - 4r direction = Into the page
