Homework Statement
Two long, straight, parallel wires, 10.0 cm apart carry equal 3.78A currents in the same direction. Find the magnitude and direction of the magnetic field at point 15.4 cm above one wire.
Homework Equations
B= ([tex]\mu[/tex]_{0}I)/(2[tex]\pi[/tex]r)
[tex]\mu[/tex]_{0} = 4[tex]\pi[/tex] * 10^{7}
Use the right hand rule to find the direction of magnetic field
The Attempt at a Solution
(4[tex]\pi[/tex]*10^{7})*3.78 / (2[tex]\pi[/tex]0.154) * cos([tex]\theta[/tex])*2
I'm not sure on how to go about solving this problem
