Suppose that P, P2, P3 and P4 are infinite current-carrying wires extending into the z direction, and carrying currents I = I, I2 = I,I3 = -I and I4 = -I. Positive currents flows along the z direction whereas negative currents are anti parallel to z. Find the expression for the x and y components of the magnetic field B at the coordinate of P4. Hence, calculate the value of the magnitude and the angle of the magnetic field B at the coordinate of P4 considering a = 1 m andI = 1 A.[25] Suppose that P1, P2, P3 and P4 are infinite current-carrying wires extending into the z direction, and carrying currents I = I, I2 = I,I3 = -I and Whereas negative currents are anti parallel to z. Find the expression for the x and y components of the force per unit length f that P1,P2, P3 and Pa excerpt on P4.
