Working of an AC Generator
When the armature rotates between the poles of the magnet upon an axis perpendicular to the magnetic field, the flux which links with the armature changes continuously. Due to this, an emf is induced in the armature. This produces an electric current through the galvanometer and the slip rings and brushes.
The galvanometer swings between the positive and negative values. This indicates that there is an alternating current flowing through the galvanometer.
