One coil is used to pass the DC or AC current through the coils and the other coil just acts to carry the current from the coil. The induced current in the other coil is in different direction and thus the coil moves freely with effect of current.
Electric Motors are generally categorized as AC motors and DC motors. AC motors are supplied AC supply. while DC motors are supplied with DC supply. The difference of the power supply produces immense difference in the working principle of the motors, performance of the motors and applications of the motors.
DC motors have a magnetic field. The magnetic field can be of permanent magnet or electromagnet. The stator of the motor mostly holds the field coil. The rotor or the motor is supplied DC power through carbon brushes or through commutator. The rotor is fitted with the motor case with the help of ball bearings. On the other hand, it is compulsory to have a field mounted on the stator and winding on the rotor. Some DC motors may have an opposite configuration (Electric Motors - Boundless Open Textbook).
The shunt wound series Brushed DC (SWBDC) motor has a parallel field coil with the armature of the motor. The major advantage of the motor is that it operates at constant speed and thus it suits some industrial functions like blower fans, centrifugal pumps, etc (Classification of Electric Motors: Electrical Knowhow).
A series Wound Brushed DC (SWDC) motor has a series field coil with the armature of the motor. Such type of motor best suits high torque applications such as elevators, escalators, conveyors, lifts, etc.
Compound wound Brushed DC (CWBDC) motors has a field coil in parallel with the armature as well as a field coil in series with the armatures of the motor. It delivers constant speed and maintains high torque. It can be said that compound wound brushed DC motors combines the properties of both the Series wound DC motors and Shunt
