What is AC Generator?
Definition: The AC generator is a machine that converts mechanical energy into electrical energy in the form of alternative emf. A simple AC generator works on the principle of Faraday’s Law of Electromagnetic Induction. It has a coil of wire that rotates in a magnetic field.
Working Principle
AC generator working principle is, these are commonly referred to as alternators which work on the principle of Faraday’s Law of Electromagnetic Induction. The movement of a conductor in a uniform magnetic field changes the magnetic flux linked with the coil, thus inducing an emf.

The parts of the AC generator consists of a coil, slip rings, brushes, and a strong magnetic field as its main components.
Working of AC Generator
The coil is rotated in the magnetic field to produce a strong magnetic field. As coil on one side moves up through the magnetic field, an emf is induced in one direction. As the rotation of the coil continues and this side of a coil moves down and another side of the coil moves up, an emf is induced in the reverse direction. Fleming’s right-hand rule is used to determine the direction of the induced emf. This process repeats for every cycle and the emf produced is of alternating type.

Different Positions of a Coil
The output of an AC generator is shown above with a graph.
A – When the coil is at 0 degrees, the coil moves parallel to the direction of the magnetic field and hence induces no emf.
B – When the coil is at 90 degrees, the coil moves at 90˚ to the magnetic field and hence induces maximum emf.
C – When the coil is at 180 degrees, the coil again moves parallel to the magnetic field and hence induces no emf.
D – When the coil is at 270 degrees, the coil again moves at 90˚ to the magnetic field and hence induces maximum emf. Here, the induced emf is opposite to that of B.
A – When the coil is at 360 degrees, the coil has completed one rotation and it moves parallel to the magnetic field and induces zero emf.
Consider a coil of rectangular shape with ‘N’ turns that rotates in a uniform magnetic field ‘B’ of an angular velocity ‘ω’. The angle between the magnetic field ‘B’ and normal to the coil at any time ‘t’ is given by, θ = ωt.
