A long, straight wire lies along the y-axis and carries a current I = 8.00 A in the -y-direction . In addition to the magnetic field due to the current in the wire, a uniform magnetic field with magnitude is in the +x-direction.

What is the magnitude of the total field at the point x = 0, z = 1.00 m in the xz-plane?

What is its direction? from x to z axis.

2. Relevant equations

Using magnetic field equation B = (mu_0 *I)/2*pi*r

3. The attempt at a solution

B = (mu_o*I)/2*pi*r = (4pi x 10^-7)(8.00A)/2pi*(1.00m) = 1.6 x 10^-6 T

using the same equation B = (mu_o*I)sin(theta)/2*pi*r, but I am not sure how to continue this problem.

Can someone help me how to calculate for the direction for this B-field that goes from x to z axis?

Thanks
