A rotating magnetic field is a magnetic field that rotates in space, created by the superposition of sinusoidally varying magnetic fields that are spatially displaced. This principle is fundamental in the operation of AC motors and generators, where it induces motion in the rotor without direct electrical contact.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. It is generated by electric currents and magnetic dipoles, and is characterized by both a direction and a magnitude, which can be visualized through field lines that extend from the north to the south pole of a magnet.

AC motors are electric motors that run on alternating current (AC) and are widely used due to their efficiency, durability, and versatility in applications ranging from household appliances to industrial machinery. They operate on the principle of electromagnetic induction, where the alternating current creates a rotating magnetic field that drives the rotor to produce mechanical motion.

Generators are special functions in programming that allow you to iterate over a sequence of values lazily, meaning they produce items one at a time and only as needed. This efficient handling of data makes them ideal for working with large datasets or streams where loading everything into memory at once is impractical.

A rotor is a rotating component of a mechanical device, often found in electric motors, generators, turbines, and helicopters, that interacts with stators to convert energy between mechanical and electrical forms. Its design and function are critical for the efficiency and performance of the machinery in which it is used, influencing factors like torque, speed, and stability.
