Magnetic Field

[jeheron]

Two parallel wires are separated by a distance of 6 cm. Wire 1, on the left, carries current into the page. An equal current flows in wire 2 out of the page.

 

What direction is the net magnetic field at point A, half between the wires?

 

In our Physics course we are given the equation F=Eq, and Ed=V. I have tried for 20 minutres using the information we have been given to work out the answer. How do you do this question?

You need the equation for the field from a current-carrying wire,

[math]B = \frac{\mu_0 I}{2\pi r}[/math]

and the right-hand rule to get the direction of the field to properly add them together (they are vectors)
