Homework Statement
A rectangular loop of wire is placed next to a straight wire. There is a current of 3.5 A in both wires. Determine the direction and magnitude of the net force on the loop.
Homework Equations
F=BIL
The Attempt at a Solution
I am kinda confused here. Will the rectangular loop feel a force without the straight wire? The current will create a magnetic field inside the loop. Is this field constant everywhere? If so then i believe the forces cancel. Then you just have to find the force on the two vertical sides of the rectangular loop caused by the straight wire.
