Homework Statement
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:
Homework Equations
B = μ[itex]_{°}(i)[/itex]/(2∏r)
μ[itex]_{°}[/itex] = 4∏ x 10^-7
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
