Question
An infinitely long straight conductor $AB$ is fixed and a current is passed through it. Another movable straight wire $CD$ of finite length and carrying current is held perpendicular to it and released. Neglect weight of the wire

Answer
since the force on the rod $\mathrm{CD}$ is non-uniform it will experience force and torque. From the left hand side it can be seen that the force will be upward and torque is clockwise.
