Consider two current-carrying wires, separated by a distance d = 3.7 cm, as shown in the figure. The left wire is directed out of the page with current I1, and the right wire is directed into the page with current I2. The point P is at distance d from both wires, so the wires and the point form an equilateral triangle.
Part (a) If both wires are carrying a current of 5.5 A, what is the magnitude of the magnetic field, in tesla, at point P?
Part (b) If the current from the first wire is 5.5 A and the current from the second is 11 A, what is the magnitude of the magnetic field, in tesla, at point P?
