CAN ANYONE PLEASE HELP ME WITH THIS??? 3 long straight wires are mounted on the verticies of an equilateral triangle as shown on the figure. The wires carry currents of I1 = 6.50 A, 12 = 8.50 A, and I3 = 5.50A. Each side of the triangle has a length of 24 cm and the point A is located halfway between I1 and I2 along one of the sides. Find the magnitude of the magnetic field at point A.
