Two long, parallel wires carry currents of I₁ = 3.08 A and I₂ = 5.45 A in the direction indicated in the figure below. (Choose the line running from wire 1 to wire 2 as the positive x-axis and the line running upward from wire 1 as the positive y-axis.) 1₁ d 12 (a) Find the magnitude and direction of the magnetic field at a point midway between the wires (d = 20.0 cm). magnitude HT direction from the positive x-axis (b) Find the magnitude and direction of the magnetic field at point P, located d = 20.0 cm above the wire carrying the 5.45-A current. magnitude HT direction to the left of the vertical

Two long straight wires are perpendicular to the page and separated by distance d1=0.75 cm . Wire 1 carries 6.16 A into the page. What are the magnitude (in A) and direction (out of the page is +) of the current in wire 2 if the net magnetic field due to the two currents is zero at point P located a distance d2=3.25 cm from wire 2? Wire 1® Wire 20 (Not to scale) d2 P Give your answer as only the numerical value in the Sl units specified. e is interpreted as x10^ for use with large or small values; 1.01e2 is interpreted as 1.01 x 102.
