An electric motor consists of two parts, the stator and the rotor. In a motor, the stator is the part that remains motionless and the rotor is the part that moves. The basic principle for all working motors is the magnetic attraction and repulsion. Since a magnet no longer moves once it has attracted, a motor needs some way to manipulate the magnetic fields so that the magnets attract and repel continuously. One way to do this is to have the current changing directions. Since AC electricity alternates, it naturally reverses magnetic fields with each change.
Your setup should look like this:
When the bare parts of the armature touch the armature touches the supports, current will flow and it will become an electromagnet. The armature will then react to the magnetic field from the permanent magnet and move. As it moves, the insulated part of the armature will come into contact with the supports and the current will stop, making the armature’s magnetic field disappear, which will again cause the armature to move. As it returns to its original position, the whole process will start again and repeat, causing continuous motion and creating an electric motor.
