Question
Four current-carrying conductor are shown above forming a square with side s= 0.40m ( the wires are actually not touching each other). The current in wires 1,2, and 3 are I1= 8.0 A, I2= 10.0A and I3= 20.0A, respectively. If the Magnetic field at the center of the square is Vector B= 5.6x10-6 T k hat, where the k hat is directed out of the page, What is the current in wire 4?
Provide a positive value if it is directed upwards and a negative value otherwise if downward.
