# Total magnetic field from two long parallel wires

## Homework Statement

Two long, straight, parallel wires, 10.0 cm apart carry equal 4.00-A currents in the same direction, as shown in the figure. ( in the figure the current carrying wires are at the end of a straight 10cm line and they are each in the direction coming out of the page).
point p is at the center of the 10cm line.
find the magnetic field at point p2 which is 20cm directly above p

## The Attempt at a Solution

I have no idea how to do this, for the last problem before this it wanted to know the field 25cm to the right of p, so I used the equation B=$$\mu_{0}$$I/(2*pi*r) for each wire and used the right hand rule to determine they were both facing up so I added them. I'm confused on what to do now though.
