What is the magnetic force acting on the finite wire due to the fixed infinite wire shown here? Strategy: We cannot use formula vec(F) = i vec(l) xx vec(B) to find the force as the magnetic field created by the fixed infinite wire is non-uniform. We have to consider an element on the finite wire, find force on it and integrate to obtain the net force.
