Q2. Basic fundamentals Working principle of Induction motor
Ans. 
Induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
• Induction motor has a stator and a rotor

• Stator has a set of coils that are supplied with AC current

• This creates a rotating magnetic field which induces current in the rotor

• The rotor then starts rotating due to interaction with the magnetic field

• Induction motor is widely used in industries for various
