A current of 4.60 A is located at the origin, flowing along the z axis. (A positive current flows in the + k direction.) Find the magnetic field at the point (2.79,3.89) cm.

Enter the x and y components of the field:

2. Relevant equations

B = μ[itex]_{°}(i)[/itex]/(2∏r)

μ[itex]_{°}[/itex] = 4∏ x 10^-7

3. The attempt at a solution

used the Pythagorean theorem to find r = 0.04787

used ampere's law to find B = 1.92x10^-5 T

found θ at 54.35°

from there i found

Bx = Bcosθ = 1.12x10^-5 T

By = Bsinθ = 1.56x10^-5 T

not sure where i'm going wrong, thanks
