Homework Statement
A rectangular loop of wire lies in the same plane as a straight wire, as shown http://i30.tinypic.com/347fupw.jpg". There is a current of 2.5 Amperes in both wires. Determine the magnitude and direction of the net force on the loop.
Homework Equations
Not sure. I am pretty lost. do i use the equation for the magnetic field of a straight wire = (μ_0/4pi)*(2I/r)?
The Attempt at a Solution
i am thinking find the electric field of the wire to find what the field will be on each point on the loop and from there find the force on each point on the loop. then, maybe i can use an integral to add all the forces on the loop to find the net force?
as you can tell, I am very lost, and a little behind in class. If you don't want to answer the problem (with explanation), maybe you could point me in the right direction. any help is appreciated.
thanks
