10:00 12 In Fig. 29-43, two long straight wires at separation d = 16.0 cm carry currents i = 3.61 mA and i = 3.00i, out of the page. (a) Where on the x axis is the net magnetic field equal to zero? (b) If the two currents are doubled, is the zero-field point shifted toward wire d toward wire ? or unchanged?

Two parallel infinite current carrying wires are separated by a distance d. Point A is at a distance R from wire 1. If d = R and I₁ = I₂, the direction of the magnetic field at point A is: Wire 1 X у -Z +Z X AR |₁ The given is not sufficient The magnetic field is zero d Wire 2 2

As shown in the figure below, two long parallel wires (1 and 2) carry currents of I, = 2.96 A andI, -4.75 A in the direction indicated. (a) Determine the magnitude and direction of the magnetic field at a point midway between the wires (d- 10.0 cm). magnitude HT direction ° counterclockwise from the +x axis (b) Determine the magnitude and direction of the magnetic field at point located d= 10.0 cm above wire 1. magnitude HT direction counterclockwise from the +x axis

A long straight wire sits on the z-axis and carries a current of 8.22 amps in the positive z direction. Find the magnitude of the magnetic field produced by this current at position (x,y,z) = (0.646 m, -4.24 m, 2.6 m). Answer in units of T.
