A long, straight wire lies along the y-axis and carries a current I = 8.00 A in the -y-direction (Fig). In addition to the magnetic field due to the current in the wire, a uniform magnetic field B0 with magnitude 1.50 X 10-6 T is in the + x-direction What is the total field (magnitude and direction) at the following points in the xz-plane:
(a) x = 0, z = 1.00 m;
(b) x = 1.00 m, z = 0;
(c) x = 0, z = -0.25m?
