Expert Answer:

Slip rings are used in AC generator to access the induced emf in the coil .
The coil (called armature) is mechanically rotated in the uniform magnetic field by some external means.
The rotation of the coil causes the magnetic flux through it to change, so an emf is induced in the coil.
The ends of the coil are connected to an external circuit by means of slip rings and brushes , so that we get
alternating emf across the terminals connected to the brush
