Answer to Question 1

The rotor rotates when voltage is applied because the bars in the rotor become magnetic through a process of induction. The rotor begins to turn when the unlike magnetic poles between the rotor and the stator attract and the like poles repel.

Answer to Question 2

The squirrel cage rotor has bars in it that become magnetic and act like bar magnets in that their fields have polarity. They attract and repel of the magnetic field in the stationary winding which make the rotor spin.
