###### FREE Expert Solution

Magnetic field around a conductor:

$\overline{){\mathbf{B}}{\mathbf{=}}\frac{{\mathbf{\mu }}_{\mathbf{0}}\mathbf{i}}{\mathbf{2}\mathbf{\pi }\mathbf{r}}}$

Right-hand grip rule: The thumb points in the direction of the current, fingers curl in the direction of the magnetic field.

(a)

Using the right-hand rule, the magnetic field at c due to the top wire is into the page. The magnetic field due to the lower wire is out of the page.
