The forces acting in a vertical direction or in a straight direction is called vertical force

Vertical is a relative term. It usually refers to a direction pointing in the opposite direction of Gravity.

So if you are in outer space, then I guess there is no real "vertical" direction.

To know the direction of the torque acting on the coil, whether the coil is vertical or horizontal, you will compare the direction of the magnetic force or its rotation to the direction of the coil. If the coil is vertical and the magnetic force is in the direction of the coil rotation, then the direction of the torque will be the same.

the horizontal motion and the vertical motion are independent of each other
