Homework Help: Physics - Verification

Posted by Robert on Sunday, August 12, 2012 at 11:12pm.

Two long straight parallel wires separated by a distance of 20 cm carry currents of 30 A and 40 A in opposite directions. What is the magnitude of the resulting magnetic field at a point that is 15 cm from the wire carrying the 30-A current and 25 cm from the other wire?

So I figured out that it's a triangle that forms with 25cm as the hypotenuse (distance between wire 2 and B)

From here I'll use B = mu_0 I / 4pi r

For Wire 1 I get 20 mu_T
For wire 2 I get 16 mu_T
so together I get 36 mu_T

Did I do this right?

Thank you
