Self-induction is called the inertia of electricity because it reflects the tendency of an electrical circuit to oppose changes in the current flowing through it. When the current through a coil changes, the magnetic field associated with it also changes, which induces a voltage (back EMF) that opposes the change, similar to how inertia in physics resists changes in motion. This property is fundamental in inductors and plays a crucial role in the behavior of electrical circuits, especially in AC systems.
Split Phase Induction Motor.
When a current in a coil increases or decreases, there is a change in magnetic flux linking the coil,an e.m.f. is induced. This is called self induced e.m.f. and the process is called self induction.
An induction generator is not self-starting; it requires an external power source or an initial starting mechanism to reach synchronous speed. Once it reaches this speed, it can generate electricity by feeding energy back into the grid or a connected load. Typically, induction generators are used in wind turbines and other applications where they can be driven by a prime mover to achieve the necessary conditions for generation.
Yes, that is one of the major advantages of a three-phase induction motor.
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?

self induction occurs in an Inductor itself. Self induction happens because of the flux change in the circuit due to varying current of the same circuit and not the current change of some other circuit thats why the term "self" is usedEngr. Saif Ali Solangi

inductor is a electronic component that resist a change in the flow of current inductance is that property of inductor.
A three-phase motor has a steady rotating magnetic field generated by the stator coil, and the rotor just follows the field.
1. self- induction2. mutual- induction
Single phase induction motor is not self starting because, when the main winding is excited from a single phase supply, it produces an alternating magnetic field instead of rotating magnetic field in two phase and 3 phase induction motor. According to double field revolving theory any alternating vector can be resolved into two vectors rotating in opposite directions, each having magnitude equal to one half the magnitude of the actual vector. The vectors will be rotating in such a way that their resultant will be zero at every instant. Thus a single phase induction motor fails to produce a net starting torque, and is not self starting.It can be made self starting by any of the methods below1) By using an aux winding in series with a very high resistance2) using two capacitors,in series with the aux wdg,one with intermittent duty and the other one with continuous duty3) Using shaded poles
'Induction' describes the process by which a varying current in one conductor 'induces' a voltage into either the same conductor ('self induction') or into a nearby conductor ('mutual induction'). Mutual induction is the process by which a transformer works.
