1. The problem statement, all variables and given/known data
Two wires with the same intensity but with opposite directions.
The magnetic field of the middle line between the two wires is:

a) (X)
b) (o)
c) Parallel between the two wires
d) Null
e) Non of the above.
2. Relevant equations
N/A

3. The attempt at a solution
Knowing that they both colide in the middle since the top wire goes (X) on the bottom and (o) at the top, while the bottom wire does the opposite.

I can't figure if it's Parallel or Null. Can someone explain me which one is the right one? I used the right hand rule.

The place they're asking about is below the top current, and above the bottom current.
Yes, the top current makes B inward (x) there ... what does the bottom current do there?

btw, it is "same Indicated current" I, but in opposite directions.

both currents make B there into the page ... can these contributions cancel?

I did this to understand a little more, They both go to (X)... I was confusing this with wires that go in the same direction.

well, the wires just sit there, not going anywhere ... it it their currents that go left and right.

Yes, I managed to figure out thanks to you all, Thank you.
