• This induces a current in the rotor, creating a magnetic field

• The interaction of the two fields causes the rotor to rotate

• Induction motors are commonly used in industrial and residential applications

DC motors use direct current to produce rotational motion while induction motors use alternating current and electromagnetic induction.
