Question

Two long, parallel wires carry currents of I, = 3.45 A and 1, = 4.55 A in the directions indicated in the figure below, where d = 25.0 cm. (Take the positive x direction to be to the right.) PLEASE COMPLETE ONLY PART (b) FOR CREDIT. PART (a) CAN BE LEFT UNDONE. 10-----1--12 bed (a) PLEASE SKIP THIS PART. PART (a) IS WORTH ZERO POINTS! Find the magnitude and direction of the magnetic field at a point midway between the wires. magnitude ит direction º counterclockwise from the +x axis (b) Find the magnitude and direction of the magnetic field at point P, located d = 25.0 cm above the wire carrying the 4.55-A current. magnitude ит direction o counterclockwise from the +x axis
