Question
Two long, parallel wires carry currents of
magnitude wo long, parallel wires carry currents of I1 = 3.06 A and I2 = 5.10 A in the direction indicated in the figure below. (Choose the line running from wire 1 to wire 2 as the positive x-direction and the line running upward as the positive y-direction.) Find the magnitude and direction of the magnetic field at a point midway between the wires (d = 20.0 cm). Find the magnitude and direction of the magnetic field at point P, located d = 20.0 cm above the wire carrying the 5.10-A current.Explanation / Answer
(a) magnetic feild at midway is 0. because magnetic field due to both wires cancel each other.
(b)magnetic field due to infinitely long wire at distance d is (
