Explanation:

Step1: Recall the right - hand rule for magnetic force

The magnetic force on a current - carrying wire is given by $\vec{F}=I\vec{L}\times\vec{B}$. The direction of the force can be found using the right - hand rule. Point the fingers of your right hand in the direction of the current ($\vec{L}$) and curl them towards the direction of the magnetic field ($\vec{B}$). Your thumb will point in the direction of the force.

Step2: Identify the current and magnetic field directions

The current in segment 1 is in the $-x$ direction and the magnetic field is in the $+z$ direction.

Step3: Apply the right - hand rule

Point your fingers in the $-x$ direction and curl them towards the $+z$ direction. Your thumb will point in the $-y$ direction.
