wo long, parallel conductors carry currents I1 = 3.00 A and I2 = 5.00 A, both directed into the plane of the computer screen as shown in the figure.
(a) Determine the magnitude and direction of the resultant magnetic field at a point midway between the wires. (b) Find the magnitude and direction of the magnetic field at point P, located 20.0 cm above the wire carrying the 5.00-A current.
