Explain the function of the following part of electric motor
(i) Armature (ii) Brushes (iii) Split Ring

Explanation

### Step-by-Step Solution

1. **Armature**:
- The armature is a crucial component of an electric motor. It consists of a rectangular iron core that is wrapped with a copper coil.
- When electric current flows through the copper coil, it generates a magnetic field around the armature.
- This magnetic field interacts with the external magnetic field of the motor, resulting in a force being exerted on the armature.
- Due to this force, the armature experiences torque and begins to rotate, which is essential for the functioning of the motor.
