## Homework Statement

Two long horizontal straight parallel wires are 3.18 cm apart and each carries a current of 9.25 A in the directions shown in the above figure. What is the magnitude of the B-field at point P, which is at a perpendicular distance of 2.25 cm from both wires?

## Homework Equations

What is the direction of the B-field at point P? Give the angle between the x-axis and the B-field in degrees (give your answer as an angle between 0 and 359 deg.).

## The Attempt at a Solution

I did part 1, and found the magnitude of the B-field, which is 1.16×10-4 T and is correct, and then I'm stuck on part B, I think according to my image, the x and y components both will double, but it shouldn't affect my angle, but it's wrong. I think my assumption is wrong. Can anyone please help me with the angle?

Thank you very much!
