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!
