The Motor Principle: when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field.
The right-hand rule for force on a conductor can be used to determine the direction of the force experienced on the conductor: if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand.
The motor principle is used to form a precise definition of ampere. 1 ampere is the amount of current flowing through two straight parallel conductors 1 meter apart in a vacuum which produces a force 2 × 10-7 newtons per meter of conductor.
Analog electric meters (i.e., galvanometers, ammeters, voltmeters) operate on the motor principle. Electric motors are an important application of the motor principle. An electric motor consists of a permanent external field magnet (stator) and a coiled conducting ammeter (rotor) which is free to rotate within the field magnet. Brushes and a commutator (designed differently if A.C. or D.C. current is supplied to the armature) connect the armature to an external voltage source. The speed of rotation of a motor depends on the amount of current flowing through it, the number of coils on the armature, the strength of the field magnet, the permeability of the armature, and the mechanical load connected to the shaft.

A motor consists of a stator (stationary part) and a rotor (rotating part). When electric current flows through the wire coils in the stator, it generates a magnetic field, which interacts with the magnetic field produced by the rotor, causing it to rotate. This rotation is used to drive mechanical systems such as fans, pumps, or vehicles.

Induction Motor working principle?
An induction motor works on the principle of electromagnetic induction. When an alternating current flows through the stator windings, it creates a rotating magnetic field. This magnetic field induces a current in the rotor windings, causing it to rotate and drive the attached load.
Working principle of hysteresis motor?
A hysteresis motor operates on the principle of hysteresis loss in the rotor. It has a rotor made of high coercivity material like chrome steel, which exhibits significant hysteresis characteristics. The rotating magnetic field in the stator induces eddy currents in the rotor, causing it to lag slightly behind the field, resulting in continuous rotation.
What is construction methodology?
Construction methodology is the process or approach used to plan and execute construction projects. It includes tasks such as site preparation, material selection, construction techniques, and project management strategies. Different projects may require different methodologies based on the scope, location, budget, and timeline.
What is the difference between a principle and a theory?
A principle is a fundamental truth or law that serves as the foundation for a system of belief or behavior. On the other hand, a theory is an explanation or interpretation of phenomena based on observation, experimentation, and reasoning. In essence, a principle is more foundational and general, while a theory is more specific and explanatory.
What is the principle of 3 phase induction motor?
When three phase supply is given to the three phase stator winding of the induction motor,a rotating magnetic field is developed around the stator which rotates at synchronous speed.This rotating magnetic field passes through the air gap and cuts the rotor conductors which were stationary.Due to the relative speed between the stationary rotor conductors and the rotating magnetic field,an emf is induced in the rotor conductors.As the rotor conductors are short circuited, current starts flowing through it.And as these current carrying rotor conductors are placed in the magnetic field produced by the stator, they experiences a mechanical force i.e. torque which moves the rotor in the same direction as that of the rotating magnetic field. the induction motor can't run at the synchronous speed because at synchronous speed the induction motor can not develop any torque to move the rotor from its stationary position.
What is the working principle of motor?
motor works on the principle of mutual induction.

What is working principle?
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
Why is it said that generator is a motor working in reverse?
because working principle of both the things are same.The motor converts electrical energy in to mechanical via magnetic induction and generator do the exact opposite of this.And yes,you should use 'electricity generator' not only 'generator'.
Working principle of hysteresis motor?
A hysteresis motor operates on the principle of hysteresis loss in the rotor. It has a rotor made of high coercivity material like chrome steel, which exhibits significant hysteresis characteristics. The rotating magnetic field in the stator induces eddy currents in the rotor, causing it to lag slightly behind the field, resulting in continuous rotation.
