Finding the Magnitude and Direction of Magnetic Field of 2 parallel wi

[physicshelpnow]

Homework Statement

Two long, parallel wires carry currents of I1 = 2.78 A and I2 = 4.80 A in the direction indicated in the figure below. (Choose the line running from wire 1 to wire 2 as the positive x-direction and the line running upward as the positive y-direction.)

a) Find the magnitude and direction of the magnetic field at a point midway between the wires (d = 20.0 cm).

(b) Find the magnitude and direction of the magnetic field at point P, located d = 20.0 cm above the wire carrying the 4.80-A current.

Homework Equations

F=BILsin(theta) not sure if that is the one to even use

The Attempt at a Solution

tried plugging in the numbers in the above equation, but not working. Help is greatly appreciated!

Welcome to the PF.

Can you scan or take a picture of the figure and upload it as an attachment? That would help us help you with this.

And when you upload it, please show your detailed calculations using that formula, so we can check your work.
