The magnetic field at point C due to Wire 1 is:

$\overline{){\mathbf{B}}{\mathbf{=}}\frac{{\mathbf{\mu}}_{\mathbf{0}}}{\mathbf{2}\mathbf{\pi}}{\mathbf{\xb7}}\frac{\mathbf{I}}{\mathbf{r}}}$, which is out of the page.

The magnetic field at point C due to Wire 2 is:

$\overline{){\mathbf{B}}{\mathbf{=}}\frac{{\mathbf{\mu}}_{\mathbf{0}}}{\mathbf{2}\mathbf{\pi}}{\mathbf{\xb7}}\frac{\mathbf{2}\mathbf{I}}{\mathbf{3}\mathbf{r}}}$, which is also out of the page.

What is the direction of the magnetic field B_{c} at Point C?

a. B_{c} is out of the page

b. B_{c} is into the page

c. B_{c} is neither out of nor into the page and B_{c} ≠ 0

d. B_{c} = 0
