[20 Points] Four very long straight wires located on the corners of a rectangle of width a = 3 [m] and length b = 11 [m]. Point A is located at the center of the rectangle, as shown in the figure. 0 Wire-1 is carrying a current /1 =6 [A] directed into the page. Wire-2 is carrying a current /2 = 3 [A] directed into the page. Wire-3 is carrying a current ], = 3 [A] directed out of the page. o Wire-4 is carrying a current , = 5 [A] directed out of the page. Wire-1 Wire-2 Wire-4 Wire-3 a) [4 Points] Find the magnetic field vector created by wire-1 at point A. BI =[ Ji+/ b) [4 Points] Find the magnetic field vector created by wire-2 at point A. B2 =[ Ji+C 7/ [T] c) [4 Points] Find the magnetic field vector created by wire-3 at point A. B1 = / d) [4 Points] Find the magnetic field vector created by wire-4 at point A. BA = i + / e) [4 Points] Find the net magnetic field vector created by the 4 wires at point A. Brei = [TI
