Homework Statement
Two parallel wires connected to equal sinusoidal alternating currents with a phase difference of pi rad. How does the force of attraction vary with time (draw a graph)?

Homework Equations
F = bqvsintheta
F = Bilsintheta
The Attempt at a Solution
I drew the wires with currents going in opposite directions due to the ACs being exactly out-of-phase. My thought is that with the right-hand grip rule, the magnetic field lines point in opposite directions and thus cancel out resulting in no force of attraction at any point but that's wrong.
