Magnetism and perpendicular wires.

[jenx44]

how do i find the b field of two perpendicular wires.

suppose one wire is pointing out of the page and the other one is going from left to right. I am looking for the magnetic field between them.

o (wire going out of paper)

B=?

xxxxxxxx (wire going left to right)

You calculate the B vector produced by each wire alone in that point and then you sum the 2 vectors.
