clockwise
It would get stuck there because right now the armature is perpendicular to the plain where the stators are
located. A horizontal force is required to push the armature to spin.
opposite
Because the armature has spined more than 90 degrees

This armature will spin clockwise

No, it never changes
It changes when it spins for every 180 degrees, when the armature is perpendicular to the plain that the
stators are located like diagram 3.
No, it never changes.
Because this motor converts electrical energy from direct current to mechanical energy.
As conventional current flow through the coil, it creates a magnetic field. The poles of the magnetic field are
attracted by stator with like pole and repelled by the stator with opposite pole, causing the armature to spin.
